Artstyle, music and overall atmosphere are great, especially level 2 and 3 (level 1 feels more like a filler in comparison). Jump mechanic is unique but not very intuitive. Once you understand it, the leveldesign is no challenge, since you can jump through the platforms, but I know leveldesign in difficult in an 48h jam. When you reach the top, the sounefx suggest you can still jump ;)
