Thanks for your opinion! When it comes to the ending it is the last remnant of the original too daring idea for a game, where you couldn’t trust your senses neither coordination nor sight and where things wouldn’t be what they look like. Well, if you were confused by the ending you shouldn’t have trusted your eyes. ;-) I am, glad though, that you liked the animation, it took me a while to make it.
PRO TIP: Banging your head against ( meaning walking into ) a wall can help you in some puzzles.
