Also 2 minor issues:
4) Some enemies like spider do not blink anymore during invincibility (which makes it hard to dodge their pattern and confusing for new players).
5) "Basic" Controls make no sense, because with Up mapped to Jump, you cannot jump from the rope anymore. The way to fix it imo, short tap = jump, long tap = climb. Btw is the game to be played with 1 or 2 hands?
