Hey I saw your post on the main forum page and had to check this game out. A linux build would've been nice given you guys are using unity. But I went the extra mile and played the game under a compatibility layer anyway.
Anyway very cool game. The art was gorgeous and the game play was really fun. Using the mouse felt good for music as it allowed for dodging through really tight gaps. The boss fight with the demon was awesome, that is by far the most impressive animation or piece of art in the game and the music slapped hard.
I did only play for a short time though, I wasn't actually able to beat the boss because the window didn't run in full screen. I dragged my mouse off it while trying to dodge and died. The fight was good though, the attacks were very well choreographed.
Very good job, I might play more of this later to see how close I was to the end and to see more sexy art.
Btw you guys are doing yourselves a disservice. You should rate more games to help put this in front of more people because it's great.
