I liked the good music and pixel art. Enemy encounters are quite random, and it's a shame to die from such accidents. I think it would be better if the ghost had 3 lives and a life-replenishing mechanic—for example, the ability to pick up a +1 life.
I had this idea. I even drew a carrot on the screenshot that was supposed to replenish health haha. Unfortunately didn't have time to implement it. Thanks for the feedback!
