First of all, thank you for playing and for your detailed feedback!
I’m very new to pixel art and used premade assets, so I agree about the inconsistency.
I actually noticed that UI issue right after submitting the game, but I didn’t have time to fix it.
The emptiness in scenes bothered me too, but I wasn’t sure how to fill it, especially when I'm not an artist and have to find suitable assets for it. Do you have any suggestions?
And yeah, that platform in the runner level was poorly placed. I get it, and I’m really sad to hear you couldn’t reach the final level.
