Hey! I like it! I played the shit out of your game, and after stage 153 the stages stopped spawning and it just counts up without me getting to fight anymore. Guess I won the game, right? :)
Make a real game out of it, you've got a solid foundation :)
Great game, great fun! One thing I didn't understand until I read the help, was that you can combine items to increase their power. May I suggest that when you pick up an item, a highlight appears around similar items, so you understand that you can merge them?
