Very cool roguelike game, had a hard time at the beggining not knowing how it controls, but after a while it felt fine. One thing about the controls is that I don't like having to press ESC to cancel a skill, but maybe that's because I'm used to right click for that in my game. ^^u
Another minor complaint is that there's times when you can't click to move to the next room and have to use the arrow keys. Or that was my impression at least.
But yeah, aside from all that I had fun. Music is nice, animations are well done and I like the overall vibe of the game. The "resource management" aspect between MP and SP is fun too and it makes the game feel like a puzzle game of sorts at times.
So yeah, had a good time with your demo. Keep it up!
