That was a really hard game haha, very creative though.

I think the biggest problem was, with platforms, you need to time jumps at the edge, but for this you need to do it with enough time to get 4 taps in. Took me a few tries to get past the lava both times. Maybe you could switch the 4 taps for something less used like direction change or stop, or use a long press instead?
Yes. Playtesting your own games raises your skill level. Therefore, you generally want to make it harder for yourself and tend to forget that you're releasing to people who haven't reached your level yet. I initially made that mistake before releasing my first game on itch.io.
I personally have no advice to give you here. Nothing's intrinsically wrong with your game anyway (especially with the Jam's constraints). The fact that you test it shows that it can be done. It's just a call for players to get better at it.
