Glitch Survival

I have just released the first version of my game Glitch Survival for Android. I feel that the in-game controls to move the character side-to-side are currently too difficult to use. I am debating switching vertical movement to be controlled by tilt controls, but I'm looking for any thoughts or feedback on what I should do with the controls.

Also if you have any other thoughts on the game, please let me know.

Game can be found on Google Play here: Google Play Store
