This game looks epic.
Its currently in alpha but its somekind of fighting game with a characters as rabbits, hard to explain but its like a sandbox fighter?

Just watch some of his videos, just.. awesome.

This is going to be one of those games that looks awesome and i will follow the progress for years with multiple delays only to be disappointed in the end.

I've played this game. As far as I remember, it was once an open source game, I'll see if I can find it.
It sucked so bad, seriously...

Edit: That was easy, it's the same guy who made it!
