Hello I made a endless runner game for Android, I am looking for ideas on how to improve the current game, game design improvements or feedback. 

I think this game has potential because I have made some test with real people, but the game needs to improve to be excellent game. 

What other obstacles could I add? 

The game has a shop with skins, extra lifes and slowndown items. What power-ups could I add?

Any feedback is welcome, but looking for someone that had experience in monetizing  games through Ads.

Here is a video of the gameplay although on the new version I have removed birds and wind because were too difficulty to avoid:
