Very nice! I think we had a very similar concept, as we both made a game where time depletes every second and every time a enemy hits you, and you can refill it by killing enemies. I enjoyed playing yours a ton, and I loved the demon deals, that's so fun! Very good job! One thing that could make the game even more satisfying, is if you moved the camera in the direction the player is moving, so we can see a little better where we're going. Other than that, this is a solid entry!
