I'm glad you liked it. Thanks for trying it, and for showing it, and most of all thanks for finding that bug! I'll get that fixed ASAP.
The player actually has a health bar at the top-left. It also shows how many balls he has in his hands. (That wasn't meant as dirty as it sounded.) There is nothing indicating the clowns' health points, but I'm probably going to add something.
I intend to continue adding rooms with different clowns, but three rooms was about all I could manage in 48 hours.
