This is an interesting game, for sure! I love how you've captured the essence of climbing by flinging this light ball into the stratosphere. I'm on board with other people in the comments, though. It might be because I played it on desktop rather than mobile, but I was wondering if it was intentional that I can just drag the ball across the screen instead of flinging it around.
Overall, this game is great already and has a lot of potential! ^^
