So this is a cute puzzle platformer. The idea of having two different characters helping each other is a popular choice for this theme, well done.
What would have helped me understand the mechanic of limited switches earlier would have been a message saying "no more switch power" or someting when trying to switch. At first I thought the game bugged out.
You would have gotten more ratings with another title screen that shows more of the game itself. The heart is to generic and while it stands out the viewer can't image what this game is about.
