I kinda like it, creative. The problem is I saw two bugs on the game
*When you get to that devil that shoots swords you can easily place yourself on the top of the red devils, they won't damage you and you can easily beat him.
PROBABLY A BUG, I'M NOT SURE:
*When you get to the snake you climb to the medium of the small mountain and then shoot, it won't hurt you.
*When you get to the boss, and he's low health, he starts to go faster. Well you can put yourself in his way and he will change direction, but somehow he changes the direction again to me and does the same some times. In my opinion you can create a defense system which he attacks you with a sword or shield.
Anyways it's a game that has some good future.
