My very first roll made everything upside down, which honestly made it a bit hard to understand the point of the platformer scene at first. But once I figured it out, I must say it's an awesome idea to roll your level modifiers! My game uses a very similar concept, so I am really happy I'm not the only one who went with that idea!
I do have one question though: I didn't quite understand the point of collecting money and upgrading the slot machine. Am I missing something, or did you just run out of time to fully implement that mechanic?
Either way, it's a great concept and a really solid entry
