Yeah, the menu ended up being more taxing than we thought it would. I still think that it's visually really cool but we should have ignored the shaders as they don't do too much for the general aesthetic anyways. Would have helped a lot as on lower end hardware, it ended up being difficult to get into the game.
You mentioned that the jump trigger was easy to miss so you ended up spamming the spacebar. That's actually what the Hard/Easy modes were for. If you select "Hard Mode", you take a strike whenever you misclick (IE, if you soam, you'll lose right away), whereas the "Easy Mode" will allow you to spam for accessibility. This is explained in the "How To Play" section but with the menus being what they are, it's understandable that it's something that a lot of people missed.
Also I checked out your submission "Tape Collectors"... Really cool take on the idea!
