Cool art in this game. Simple combat which I enjoyed. Nice mix of melee and ranged with a variety of weapons. Intro scene was really cool looking. Main gripe is that I wasn't sure what I was doing. I'm lucky I didn't quit before I found the first boss. Finding a map on stage two made it bearable, but I think the levels were way too big for a jam. First stage should have been like 5 rooms, then boss so players could get the general idea. Second stage, maybe like 10 rooms. I died at a giant robot so I don't know how long the game was, but I wish I had made it to the end.
There were also blocks that I wasn't sure the purpose of. Early indication of what the pickups do would be nice as well. Definitely need to give players more direction, otherwise it just feels like wandering and killing endless enemies. I think if you had consolidated your game into about 1/3 of the rooms, it would have been much much improved as an entry.
EDIT: Ohhhhh they were procedurally generated dungeons!!!? That's pretty awesome. Still, smaller would have been better, especially to start.
