It's nostalgic for me, and I think there is definitely an element of "you had to have been there". I think the timing is about right that a lot of people will have these memories but it's definitely not going to hold up over time or appeal to a younger crowd. It's going to bring back memories if you've played junkware, but some features might leave people confused (particularly the crack). I'm glad that it's clicked for you.
The CD audio feature is really questionable because not many people have optical drives anymore. I think it works for this jam but it's not something I'd bother implementing for a serious game. The implementation is also disgustingly hacky and I'm amazed it works at all.
