Amazing concept! You took the classic path rotation genre, and really made it unique with the addition of enemies. I can imagine levels where you create multiple paths and try to calculate your health at each point to see if you'll be able to make it. I also really liked how one solution was about blocking an enemy path, to force them to go for the scorpion instead. The sound effects and music were also great.
I think a feature where you can "fast-forward" the little skeleton would be great. Loved the game.
