I really like this game. Look at level 3, seems that there is a glitch that if you move the directors, the just keep moving and you can't place them correctly.
I can't seem to find that glitch. I know of a small glitch in level 5 where the air will go through a platform for a bit(for some unknown reason), but it fixes itself after about 1-2 seconds. Its weird.
Edit: I made an alternate level design for Level 5 that avoids the glitch mentioned.
