I've played a few different "die to get powers / progress" games in the jam so far, but this one is my favorite -- it really feels like there's a difference in power and state between being alive and dead, and that there's tactical reasons to be each. Paired with the frantic pace of the game, it's really fun.
My biggest gripe would be the teleporter cannon things -- they shoot so slowly that it doesn't really fit the otherwise fast paced nature of the game, to the point I gave up on levels because I couldn't figure out how to time them right. Maybe I just need to git gud, but they drove me crazy.
(Also, appreciate the Linux build :) )
