I was a little confused at the start, originally trying to find the pockets to fall into, but figured it out pretty quickly after falling off. Cute little game! Not sure how you got away with painting on a bowling ball, but all I know is, I'll never play billiards against you. XD
Metagame cog 16/125 (but I think you need to check if your function is right, I don't seem to have gotten the achievement D:)
EDIT: This bug was indeed fixed, woo!
