That’s great! I downloaded the new version, the restart/quit functions are a welcome addition. However I’m afraid I managed to somehow get stuck on that level after restarting it once:
The ball doesn’t move anywhere (dragging the level still works for camera panning), no matter how many times I tried restarting with the button. The quit button still worked.
I’ll give the Android version a go soon too :)
Also I noticed that there’s a barely readable message on the game over screen that says “space to restart” or something, but seemingly Space does not restart the game. I guess this could be just removed because the restart button works fine on the game over screen.
