It's really fun. The game is good for both casually messing around with friends on hazardous stages or playing serious matches. It's a bit barebones in terms of polish and it seems more like an early-access title than a finished game, hence the 4 stars instead of 5. Voice acting would be a welcome addition (although there are already community mods for the PC port that accomplish this), and the roster needs fleshing out (which seems to be planned). Regardless, I've played the game with friends for hours now, and good times were had by all.
