This is CATDAMMIT! It's about a cat, described by the devs as "a milkoholic hobo". His milk was spilled, so now he has a chainsaw, and he is destroying everything.
It's being developed by Polish studio Fir & Flams, and will be out soon on PC/Mac. For free. Not free-to-play. Proper free.
Can't argue with proper free, especially when the game looks this neat!
