Played on windows. Seems like a really cool start to a game. It did feel intense and like I as in danger, unlike some other similar games where you can take hit after hit, it punished me for being cocky or poorly performing a move. as others have said, the combat is fun and fluid, but I feel it could be a little bit more punchy. I think the sound plays a big part in this, it's just too quiet and soft at the moment, especially the punches. would love to hear it sound more visceral, like a beefsteak being slammed against a wall.
My only other critiscism that stands out is the collisions are very buggy. Everytime I jumped, I fell through the floor, and when I died on a piece of geometry, I couldn't get up upon respawn and was trapped there until the enemies knocked me off. I'm guessing you're gonna build up the levels more, so its not really important.
Oh yeah, and I would love if target was on middle mouse button, I think it's much more natural as you're not likely to be attacking when targeting, but you will be moving and need to keep your fingers on wasd.
