Really well-made floor game. Multiple "stages" consisting of three floors each, each "stage" with its own music and visuals. Unlike most games of the genre (Crimson Needle fangames), this game's stages aren't inspired by multiple other games, but rather by multiple stages of a single game that's yet to be released. LOTS of interesting jumps, the visuals are really, really nice, and the musics are nice too. Since they change every 3 floors, they never get repetitive either. Some stages look fairly similar design-wise, but most of them have some nice details that make them stand out and the jumps aren't repetitive, so that's not a real issue.
I do have a couple complaints regarding individual saves, such as floor 49.999[...]'s last save for obvious reasons and one of the dotkid screens which features a pretty awful single jump save, but most of what I have to say about the game is positive.
It's a really cool game overall. Would recommend.
I really liked the level design and the original quality of the graphics, but some floors were way too easy or too hard compared to the rest of the game. If you don't really mind about the difficulty curve and like grinding some hard needle, I highly recommend you should play this one. Hardest game I've ever cleared up to this date.
