Planet Alpha was... an artistically beautiful but a messy game. Gameplay wasn't too interesting and the day/night mechanics that only added something new to the game was useless after a while. Movements and jumping was clunky at some points, especially in void(?) parts so I got frustrated a lot. However, chase scenes were actually exciting and put me in the game back again. Most of my score goes to environment and sounds as they were beautifully crafted and were the reason I wanted to keep going. Most of the story was happening at the background, and I enjoyed how the environment crafted a story for itself. We were running to survive in the front, while nature was fighting to survive in the back. Especially watching the flying whale family fight for themselves and seeing the mom and dad die as they slowly lose their limbs in the background broke my heart. I was happy that the child survived but then the nuke happened... Overall story and the history of the planet seems to be messy, some technological altars exist, there is a void(?) and teleporters? How did we even come here? Why are we not trying to go back home? Are the dead likenesses of us just some other people from our race or are they our failed 'loops'? And how does the 'loop' work? I know the story and the ending is up for player's interpretation but I think developers could've made a better job at conveying their visions. Still, this game made me feel a lot of emotions, especially melancholy when the loop happened and I got to see the nature thriving again, only to realize it's destined to get destroyed. I don't regret that I put 5 hours into this game and I actually recommend it but I regret to see that it could've been so much more with further world building.

Beautiful game, a little confusing story but the gist is understandable, and clunky at times due to bugs but nothing that prevents completion. The puzzles can be frustrating at times but nothing too bad. There are invisible walls out of nowhere at any given moment so you have to jump to free yourself which isn't intended, like you are just stuck running in place for no reason...not sure what caused this bug. I completed the true ending without guidance on my first and only run so it isn't too difficult to find the artifact portals needed for that even though 2 of the 4 gave rare achievements so take that as you wish. Worth a play, one of the better side scrollers out there.

This is a very pretty left to right walking puzzle game with some platforming tossed in (Limbo and the like). It runs really well and looks good doing it. The puzzles are never very complicated. The platforming is not too difficult either. There are collectibles to search out if you want to find those.

This might be my favorite side-scrolling adventure I've played. It's a cinematic puzzle-platformer in the same vein as The Cub and Planet of Lana, alternating between fast-paced set pieces and environmental or enemy-based puzzles. Like many games in this genre, it also comes with its share of rough edges: imprecise platforming, overly specific puzzle solutions, occasionally unclear direction, and a few too many moments that force you to restart. Where Planet Alpha truly sets itself apart, though, is its world. Atmospheric games often get praised for their visuals, sometimes more than they deserve, but here the acclaim is completely justified. Every environment feels thoughtfully crafted, and it's obvious how much care went into the visual design. I never fully understood what the story was trying to tell, but honestly, I didn't mind. Exploring this mysterious planet- filled with the remnants of an ancient civilization, vibrant alien flora and fauna, and the backdrop of a robotic invasion- was captivating on its own. The pacing sags a little in the middle, but I was hooked from beginning to end because I couldn't wait to see what the next area would reveal. Planet Alpha isn't perfect, but its breathtaking world more than makes up for its flaws.

Very pretty game with stunning graphics and atmospheric soundscapes. This is a 2D/2.5D platformer with some puzzle elements, where you are thrust into an alien planet scenario where you will have to get rid of or dodge wildlife and technological adversaries alike. Graphics: Absolutely stunning with many creatures and plants sporting bioluminescence to give this an almost synthwave or neon/blacklight feel, especially at night time. Sound: Atmospheric drones, beautifully crafted alien wildlife sounds and believable technology beeps and bloops to not only provide background but actually helping you survive. Gameplay: Kind of surprised about the negative reviews talking about boring gameplay. It makes me wonder if these reviewers have taken the time to actually play past the first chapter... Gameplay is pretty varied, with some tight platforming, some high-speed scenes, puzzles involving both objects and the planet's day/night cycle (and manipulation thereof), and some out-right tense action sequences with an over-arching story told purely graphically and through events around you. Overall, a very enjoyable experience and warmly recommended.
