I can see this game being more fun with the following points considered:
- Have a different kinds of jump where you can either hold for higher or tap for a shorter jump
- Let the player see more on the right side. The player does not need to be the largest object on the screen because the player attention should be on the objects that appear on the screen.
- Have some kind of background so you can see that you are moving. Especially in the beginning I was searching for controls, while the game already started.
Other than that I enjoyed it.
