this game is full of bugs. like, look at them, they're everywhere!!! Before beginning with serious part of review, i want to note that as of 25/06/2026, i've done following clears of this game/have gone this far: 1.0 Original No-Bomb for achievement 1.0 Original on Steam 1.0 Maniac on lagless FinalBurn Neo setup with 47% CPU clock Made it into TLB of Arrange mode on single credit on both PS2/360 ports And, cleared 1.5 Original on both Steam and recently dumped arcade version. So, this review is coming from someone who put a decent chunk of time into this game, even though steam's hour counter may be a bit misleading due to me preferring to play on FinalBurn Neo due to less input lag and save states that can be used for advanced practice/quick restart back to stage 1. Jokes aside, this has to be one of the best danmaku shmups out there. While i don't think i'm still good enough to take on Ultra mode, from my experience all other modes (except 1.0/1.5 Ultra, because as i said, i don't feel like i currently can take on it) allow getting both score based extra lives without needing to engage with scoring (which as far as i know is don't die/bomb, pointblank things that give extra amber and time juicy bullet cancels), allowing player to focus on pure micrododging without worrying about missing out on final score based extend like it happened in my DFK clears. Also, controls of game are simple too, allowing to focus on dodging even further: You can move, you can tap shot for rapid fire (or use rapid shot key) for wide options with fast movement speed, hold shot when you want to narrow down options for additional damage and slower movement speed to make tight movements, and if you're trapped, you can press bomb key to clear screen of bullets while damaging enemies and getting yourself i-frames to work with! You want to avoid using bombs too much though, as their supply is limited. Oh, and also there are rapid auto fire/fire keys, which are used for the "supershot" exploit, however i don't really want to go in its details, and you don't really need it to clear the game. Upon getting into menu, you get access to few modes: Novice 1.0 - Release of 1.0 arcade version with toned down bullet patterns, and doubled bombs from carriers. Normal 1.0 - Faithful recreation of 1.0 arcade version, nothing else to say. Arrange - Improved version of Arrange mode from PS2 port. Arrange mode allows switching between all 3 shot types on fly, gives you max firepower with additional 2 options at start, you get autobomb with smaller hitbox, and patterns are a middle ground between Maniac-Ultra, with toned down secret encounter waiting for you! Personally, i still prefer PS2 arrange more, mostly because this one forces you into 1cc and has a secret text line that plays when you use stage restart function at least once (even if in my example it was on stage 1): https://steamcommunity.com/sharedfiles/filedetails/?id=3729220928 I really wish more CAVE games had such 4th wall breaks, as it would be nice to make something similar play at end of game if player used more than single credit in a run. 1.5 Normal - If you own 1.5 DLC, you can play the 1.5 version of game! This one contains absurdly broken scoring system on Maniac, made weakest shot in game absurdly strong, nerfed formation options, updated visuals, made every enemy in game bleed amber on pointblanking, and re-arranged the stages, filling them with more enemies, adding extra slowdown that you love. Oh, and if Maniac/Ultra were not hard enough for you, you can pick the MAX option at start of run! This one, as title says, gets you to MAX power (with addition of actually useful formation options), at cost of enemy bullet speed/density being doubled. Also, as a fun fact, this mode was originally not planned in 360 port, however due to 1.5 being ported before greenlight, Ikeda just decided to go with it. After selecting mode and getting into game, you're asked again to select mode (outside of Arrange): Original - Mode with less denser bullet patterns that utilize faster bullets. Recommended for first 1cc! Oh, and bullets appear to have slight ghosting/motion blur effect to them. Maniac - This time, bullets are much more denser, however their speed is much slower, and scoring system is different. Recommended for people who are into bullet hells, also just like Arrange mode contains my favorite pattern in entire game, on stage 3 boss, it's final pattern is the first thing i think about as bullet hell. Ultra - Joke mode that was made to either get em credits off players, test limits of human body/mind or to show off capabilities of new CAVE CV1000 hardware that was also locked behind 1CC in original arcade release. If you can get far enough, a secret will wait for you! I also heard that Original and Maniac/Ultra have different hitbox sizes too, though i can't fully confirm it. Now, that i covered All the aspects of game that were worth mentioning (outside of presentation, as it's really a thing that you have to decide for yourself), now time to go with technical side! Input lag is alright, isn't that bad, but it can be improved a bit. Just be sure to use Special K/dgVoodoo2 to reduce lag a bit there. Practice features are highly customizable and allow to recreate just about any scenario you want. You can also customize screen settings too, allowing to select your prefered aspect ratio with screen rotation and advanced scaling settings! For non 4:3 monitors or if you have additional screen space remaining, you can use it for score/input display. Not the M2 level, but it did its job for time of port release. For bad parts regarding technical side of this port: Your replays desync a lot, and i'm not joking. Just looking at them wrong is enough for these sensitive ♥♥♥♥♥♥♥ that put my infected hand to shame to desync! For some reason, trying to open friends leaderboard crashes my game. Or maybe it's one of my friends who should be drawn as a pregnant man for putting this curse on me. fullscreen issues are expected since this game utilizes d3d9, but i still want to mention it there. You may want to grab dgVoodoo2 to account for these issues! Overall, game itself offers decent amount of content to explore for both novices and experts, and port itself is a great package with decent amount of options for customization to work with.
