Very few games can ever claim to be the digital equivalent of learning how to ride a bike: the kind of high learning curve experience in which you will fall to the ground several times trying to learn how to ride it, but once it clicks, you feel like the carp that swam up the waterfall to become a dragon. This is what it takes to become a Bioranger of the Baionlenja Corporation. Baionlenja is a unique game that takes the movement based puzzle chamber gameplay of the likes of Portal and swaps the portal gun with bunny hopping and a sword that allows you to perform rocket jump-like maneuvers. The concept is simple but mastering it is a different story. Bunny hopping, an advanced movement tech seen in some of the oldest full-3D first person games such as Quake, are a mandatory skill that the game will slowly train you to use and it WILL expect you to get to grips with the technique or else you will not make it past the first level let alone the tutorial. If this sounds intimidating, don't worry, the way the game teaches things allows you to practice until you get the hang of things. Just remember: the faster you go, the slower your mouse movements should be, and you don't have to strafe the whole time, just when you want to gain speed! The puzzles are engaging and there's a lot of interesting setpieces such as the dreaded poison swamps and that one scene where a giant robot chases you down a hallway! Not to mention, the atmosphere in this game is PHENOMENAL. It's not quite a horror game, but it's definitely scarier than something like Portal. The best thing I can compare it to is the obscure 3DO FPS Iron Angel of the Apocalypse. In that game, you're a human stuck inside a robot traversing a gritty techno tower full of assorted mechanical experiments turned into weapons all to the tune of a soundtrack with a foreboding atmosphere. That's what both that game and Baionlenja get right: a forboding, avant garde industrial sound that immerses you in its bizarre world; Baionlenja also happens to mix the existential dread with a good balance of humor. It doesn't overstay its welcome and only adds to the strange aura the game immerses you within. There's times where you will walk into a cool setpiece and the game will troll you with a "Pre-rendered footage, not real gameplay" message on the bottom of the screen... as you're walking around. Something like that feels like the kind of gag on par with the HIDEO screen during the psycho mantis fight in MGS1. If I were to suggest anything, however: I feel there's not enough to really threaten the player. I believe a good balance of enemies can really help give the game variety (you're running around with a blade, you kinda NEED to have enemies to swing it at), but none of the enemies and ensuing conflicts are really that interesting in the current EA version I played. Maybe it's because you only have one method of attack, or maybe it's because the most enemies you get are the largely harmless canisters, but I felt we could have used more encounters where you have an enemy that stands more of a threat against the player. Even the setpiece with the robot didn't feel very threatening outside the cool factor because it was too slow compared to the player. One combat encounter I really enjoyed however was that one area that consists of a small maze in which you're pursued by a bipedal foe that shoots lasers at you and you had to learn to bunny hop in an enclosed space to evade and attack it. It's a very short encounter, but more moments like that would be amazing. maybe a scene like that with more enemies, or a stronger version of that enemy but with more HP. There's so much potential for combat that I feel is untapped in this current EA version, it's a shame the game only hints at it but shies away from it all. Speaking of shying away from combat, Apparently before this version, the game had a gun to accompany your sword. This was removed entirely out of a desire to focus more on the sword. I can understand the feeling that a gun would be pointless in a game where you can outrun everything, but it feels like a missed opportunity by just scrapping the gun altogether. You could probably use a gun for puzzles like hitting switches or perhaps a different kind of gun like a limited range lock-on laser of some kind. if there is to be no more firearms, it would be a shame, but I'd love to see some additional abilities and evolutions to help compensate for it, especially extra moves for the sword or anything to be mapped on right click (it is supposed to be a metroidvania after all, they gotta have more evolutions and a bigger map to promote that metroidvania promise!). I just can't help but feel like I missed out on something here, and I wonder if the remaining levels beyond EA will keep the same exciting momentum these EA levels have, but I'm sure there's plenty of surprises in store for the final release. Overall, Baionlenja is a very promising game with unique visual and audio design paired with challenging gameplay that might turn some people away who can't adapt to bunny hops, but if you stick to it, you'll be wanting more. Also holy crap this game is optimized like a dream, it runs super smooth at all times I love this aaa
TLDR: great base, great vibes, great movement. I did not enjoy the level design though. Despite the fact that I didn’t really have fun, I’m leaving a positive review because I believe one day I could have fun. This is a parkour game, you would think that means “gain a lot of speed, make cool jumps” unfortunately the game doesn’t really seem to agree with that. They made the act of gaining speed fun, I’m not experienced with Source games, but “Bunny hoping” is intuitive, and from the tutorial I had a vision of wide open levels, where the challenge is going to be how to control the speed that you get. About 1/3rd of the levels are like this. The other 2/3rds seem to hate the fact that you can gain speed at all and will do everything in their power to slow you down. Theres a level in this game that’s entirely cramped corridors with monsters roaming the level. I cannot understand why you would restrict movement in a parkour game. 1/3rd of the way through the game you get effectively air dash. It halts all your momentum, and applies force in whatever direction your character is facing. Adding this into the game was a terrible decision, because the entire rest of the game now includes precision platforming, it’s just another way the game stops you from going fast. The vibes in this game are immaculate though, I’m a big fan of megastructures and bleak environments, and this game delivers on both fronts. The atmosphere is sufficiently eerie, and the sound design works really well.
Whichever year this game comes out in 1.0- Every OTHER game that year is gonna have a one hell of a competitor. Because to me this little game is a prime GOTY material, and this is coming from someone who never cared for movement based games - Baionlenja is just THAT good. It is dripping with style, from its monolithic structures, to its eye-catching colors and Bionicle-inspired designs that invite curiosity, intrigue and a desire for exploration. It feels vast, desolate, yet full of mystery, serving an as-of-yet unknown set of functions that the scant recordings only allude to. The voice of the Fossil, Gehirn, is executed beautifully, and it goes hand in hand with that absolute banger of an OST. I just cannot get enough of it. The gameplay itself was something I would have never expected to fall in love with. Yet, here we are. You've a small set of abilities that allow you to whiz through the air like a bullet at the speed of sound, and reckless abandon. It is easy to learn, but incredibly hard to master. While the game does not throw impossible challenges at you, there are multiple side-challenge levels that will ABSOLUTELY test your patience, nerves and skill, and are a blast to slowly dissect, decipher and - eventually, overcome. I also love the bits of absurdist humor, peppered throughout the logs. My biggest criticism as of yet, is the lack of levels - I'd say it could use 3 or 4 additional challenges to go through. Would also be fun to have a level select option, as it takes a while to reach some levels. I also think some areas just get a bit too dark, to the point of being pitch black. A bestiary would have been nice too, as the logs reference a lot of machines, but connecting the text descriptions with the actual designs of mechanoids is a bit difficult. All in all, the package is small, incredibly stylish, and it just oozes atmosphere. There is very little for me to criticize. Hands down, one of the best games I have played in years - I absolutely recommend it.
Baionlenja is a game you'd likely only discover through a handful of niche interests, but the dev is working seemingly tirelessly to make it accessible no matter which particular part of it draw your interest. Down to making an older version of the game available through steam branches when interest was expressed. If you're into the bhopping or rocketjumping, it may be a little easier than you'd expect, but the level designs allow for skilled players to optimize their movements, while players who may be intimidated by learning such techniques can still make their way through just fine. If you are into the horror aspect- the older versions of the game available on itch.io mightbe closer to what you're looking for, but the current version has it's moments too. I went into baionlenja thinking a game where you can triple your movespeed in 1 simple movement wouldn't be able to get under my skin, but it managed. If you're into the exploration aspect, baion already has a history of secrets that I won't get into because that defeats the point. If you read the bionicle books as a kid, yeah. I'm not typically a review writing, so this one sucks, but I'm doing so because I want this thing to be as worth it for the dev. That's the most I can concisely say about it's worth to me.
