I enjoyed the graphics and music, and the sound effects were spot on. The story and NES-style intro cutscene were well-done, and the game was pretty flawlessly put together. My only issues were that the jump seemed a little floaty, and sometimes if you fall and try to jump again immediately you only do a tiny hop. More than once this made me accidentally jump straight into a hole. Apart from that, I really liked it. I think my favorite things were the creepy monochrome background art contrasted with the cute pastel colors of the main character.
