It starts well and gets progressively worse. I really liked it in the beginning but the more you progress, the more uninspired it gets. Enemies always repeat themselves and the level design becomes frustratingly bad to the point where it just isn't fun anymore. Difficulty also increases a lot and it becomes really hard but not in a fun way. It's a great example of bad level design. The soundtrack is also more annoying than anything. Kinda sad since I like the design of Mr. Nutz as a platformer mascot.
