Cool concept but I kept hitting a bug where all the obstacles would disappear, it would thank me for playing then quit. Bugs are to be expected in jams though and I can see that this deserves a good rating :)

Well this is the intended behavior when you roll over the exit-letters in the menu, but you are not the first one who reported that kind of behavior appearing pretty much all the time although we never experienced this ourselves (Although the menu is a bit buggy at times xD).
Many thanks for the feedback! :)
