Well, putting a full screen option was needed but having to press esc to quit the settings makes the fullscreen go away. You should probably enable the site's full screen button that is in the bottom right corner of the screen in other games. I often got stuck, in some levels timing the falling of the character was enough to get me out, but i could'nt find a solution at one level, i felt like i was limited on how fast i can turn the orientation to complete that level. The level where i got stuck was where there are singular spikes periodically on both sides and i had to fall. The idea was original, but i've seen at least 2 other entries already using a ball in similar fashion, but yours is the best of them, as you have story too, and the visals were nicely made, sounds too :)
