this absolutely a genius idea, and I love how well everything fit together, especially how you showed all 4 games that you would be pressing A for in a row before making you actually do them, can't wait to see more genius ideas like this in the future (Easy sub)
I’d just add some visual indicator for when a screen freezes or unfreezes, like a small countdown along the top before it happens. Also then the screens are moving all over the place it’s probably intended to be really hard to track but I feel like it’s way too unfair
This is a cool idea, I think it'd be fun to play around with it a bit more: in particular, with the multiple-game segments I think it could be cool to either cut out the setup bit so that you have to react to the situation on the frozen beat, or make it so that the screen goes dark when it unfreezes so you have to remember what inputs you have to do based on the setup.
Make the DJ School intro like Spaceballs, where it doesn't start until you hit like 4 out of 6, so it's practice without taking the time for every game.
