Had a few goes of it there
First off, I'd add a description or objective text somewhere in the app. I realise now you had it on the store page but I wasn't aware the idea was to go up as much as possible and the first few times I just went around in circles.
The core mechanics are very tight and well done, the hover gives just enough to keep you in the game, and you can see quickly which direction you should be going in when you get stuck. Maybe a legend of what certain items are would be good too? Checkpoints were avoided the first times I played as I thought they would kill me
Art assets are pretty well done, and your UI is actually pretty good. Mind you I've a large phone so not sure how cluttered it might look on a smaller screen.
Bought the unlimited continues as I believe any game dev work should be encouraged.
