Good game, I liked everything, made it to current end point (new password). I even jumped in small vent space in the opposite wall from the third propeller (and found nothing... I thought there was a secret room). Wish it was finished, because everything was good, fun to play, and satisfaction when you free up legs and start run fast.
So far i found 2 bugs:
You can accumulate speed and jump height impulse if pause the game and press corresponding button for long enough.
If got caught after freeing up arm completely (at end point) - tape on mouth will be restored.
