Super great game! I think it was really creative that you staggered out the beat like that instead of doing a straight beat like a lot of other rhythm games. And I really dig the music! You're right, it is kind of funny that we both use the same off-kilter beat in our hardest song! Wanted to add more complexity to the game beyond just spamming more notes, eh?
Personally, I'm not a fan of the controls. I guess it makes sense to make the game one-handed, but I could never manage to remember which button jumps and which one switches sides. And it felt like I had to be airborne before I even crossed the white boxes, which meant I had to press a fraction of a second ahead of the beat, which felt awkward.
