Amazing game, with potential! I do have some ideas that might make the game better. First. Add a (add layer button) meaning, put one type of block in single layer, covering the whole area(kinda like a baseplate)
Second. Add some new types of enemies like giant spiders and a cat warrior boss.
Third. Please add a sound track and trigger so a music or sound will play when the player walks over it.
