I have been playing the amazing EXAPUNKS game lately, and having a ton of fun.

Writing some assembly-like ultra limited language is how I started coding when I was a kid, so this game brings me back! Also the whole 90s hacking scene theme, oof, goosebumps.

I still haven't completed it, but I will post here my solutions up to where I am currently at in case they can help anyone!
