Haste is really fun. There's a first person mod (in the Steam Workshop, I think) that makes it better imo

Yeah I tried Haste last next fest before it's release too...just judging off the demo, it's a good idea but not my kind of game. The roguelike mechanics don't really add that much to the whole game, you're still going to be doing practically the same thing.

But it was fun enough, just not enough to get me to buy it.
