I agree with you, I should remove that black screen. I originally went to do that because my initial idea was something like player enters numbers and he has no idea what he really enters, and he has to deduce by rng he enters(But that idea doesn't make sense anymore because of the way it evolved). Wish I could see bad parts of the idea and reconsider them during the jam, haha.
So a great idea with just a confusing execution, I get it now. You could really benefit from a professional game-designer's second opinion in cases like these
Innovation and cool concepts are great, but your ideas must never become style-over-substance. A game must still be fun to play, no matter how nonsensical, unimaginative etc. that would make everything else
Great ideas require great execution to work, and that is a game-developers and designer's eternal balancing-act
