Hey, thanks for your feedback.
The gap between the songs comes from the pause on game over and will be fixed once i get around to make an update.
The physics, especially the slow fall was a descision, as faster felt odd aswell.
You can, in fact drop another cat when one is in the air. But there is a delay in dropping cats.
Regarding the shape of the glass, the physics follows the drawing. Any other way would look even more ridiculous :D.
Hope you're having fun anyway.
Toodles~
