I wanted to like this but it kind of felt too simple? I suppose the next world could introduce more depth with different items, but the basic movement and using interactables seems pretty one-dimensional. 99% of the time you can only move left or right which means you have less control than Super Mario Bros. (I don't know if items will become way more common in later levels)
From the comments, I think you just introduced rotating and movement as two separate keys for that one selection? Obviously you know what you're doing with your game more than me but I'd suggest just making that the only option and leaning more towards that Trials/Happy Wheels kind of thing. I'd want to be able to rotate on the ground, do wheelies and have to really care about managing my weight and rotational velocity, and hitting slopes correctly.
I also really didn't like how the rotation speed in the air takes a moment to kick in and then has no velocity/inertia. It would probably feel way more satisfying if it just increased in speed the whole time you were holding it (with a speed cap or friction so you can't rotate TOO fast). And then had inertia so you really had to line yourself up with the ground before landing, basically like Trials/etc.
It could just be that you're trying to make a fairly casual game and it's just not for me, though. These are mostly all suggestions to add depth (and the possibility for frustration) that you might not want in your game.
