Maaan, I'm so glad you noticed the music tweak! That's the "minor" thing I love. x) Love your feedback overall as well.
And I do agree a lot with enemies. x) Some other people from my friends noticed it as well, and I frankly think there should've been more amount in general. I planned to have a cool flat part of the platform where you'll just knock 10 enemies and get some juicy visual feedback (didn't plan any buffs at all, at least for the game jam timeline); but I completely forgot about this idea, lol. x))
I really like the idea with enemies throwing the shopping cart - that's sick! I'd really consider adding it. Fits the vibe totally. Will think about it.
About the breaks, well, the other comment pointed it as well but I kinda don't really feel it. The main mechanic is about changing speed so abrupt breaking is a part of it, hm... My friend, however, said that it might've been the problem of the 1st biome, because I intentionally made it quite simple, so you can finish it whole without changing the speed, and even on max speed only. So that might've taught the wrong idea that you should pass the whole game on max speed. But then it would be another Geometry Dash, huh x)
What you think about it? You would want it to have just less breaking points, right?
Again, i'm so glad to receive such a feedback, daaamn! I really wanted more of that. x)) I guess, it was mostly the problem of the game picture/game page/screenshots that it din't bring that much attention. Well, it's a thing to learn. :)
