This was fun and a super unique Idea! I did notice that I wasnt dying on contact of spike I would have to move around for it to register to kill me. Super cool though!

This is fun! I'm impressed by how much you made out of a very simple mechanic. 

I wish the rules of movement were slightly better communicated/defined. I figured out that getting a running start makes you go higher pretty early, but the movement sometimes felt a bit unintuitive.

Also, you might be aware, but the spike kill boxes are a bit too small in places. I saw the spike animation but didn't die a number of times.

I do love the little shadow visual effect on the player. It makes a visual style that's basically "oops all orange" look really slick!

Great game . The level transition and music were very cool . Impressed by how many level you have made in such short time .

Great submission, easy to understand,  good music, and fun premise.

If you were to develop this further I'd look to tighten up the controls a bit more as the jump feels a bit floaty, 

And since you're already displaying your number of jumps, why don't update the text with the number you currently have.

This could be a fun mobile game well done.
