Few things I would add / consider.
- The Menu after you get hit should have 2 buttons. one that goes to MainMenu and a second button that just reloads the playable level. (Right now you have to press 3 UI buttons to replay after you fail the run)
- When the player jumps... for about 1 frame the player is shown in idle but at no point did the player stop moving forward, looks a little strange.
- Music
- Possibly more obstacles or even powerups (like speed / jump boost)
- The Player is in the middle of the screen's y position but I don't see any reason to look very far below the surface because once your down there the run is basically already over. you can probably increase the height of ball spawns to match the new height too. Something like this.
