This hack varies from low-mid intermediate difficulty for any%, to 100% which is very tough but rewarding to complete. One of my favorite parts of this game is that it features a pretty generous checkpoint system, therefore even if a move or two is frustrating, you don't lose that much progress and it keeps you motivated.
The walkman feature, although I didn't use it very often, is a nice touch for people who may get tired of a theme, especially if they get stuck in a level, allowing them to have something else to listen to. The overworld also allows you to choose any level you want to, so you can pick whatever order you prefer.
Overall I had a pleasant time with this hack, even though a couple levels kicked my ass during playtesting. Thanks for giving me the opportunity and being very responsive to feedback, and I'm looking forward to anything else you create in the future! <3
