I love the art and presentation. The key art drew me in, and the little manga-esque storyline at the beginning was great. The in-game art and music give it wonderfully calm and melancholic atmosphere.
It does bother me more than it should that Maju has gloves in some of the art but not others. Did the character design change slightly during development? I think this is an example, though, of a case where the minor issues only stand out because it's generally very well done.
I was really excited to play this game- a tetris- esque puzzle game in a sea of shmups- but unfortunately I couldn't get a hang of the mechanics. I'm not sure if there's something I'm missing or if I just ran into some bugs. Some colours of blocks disappeared when I stacked a few, but others didn't even when I stacked them even to the top. Sometimes they'd disappear anyway, maybe when I stacked the same colour beside them, but it didn't seem to be consistent. When I hit the top, the game didn't end, but new blocks started stacking into the middle of existing stacks. I thought part of the game was cut off at the bottom and there was stuff going on down there, but from the official screenshots it looks like that's not the case.
