Ahaha, this was a fun little thing once I knew what I was doing. Apparently I couldn't figure out for a bit that "on the line" meant put the cookie on the line in the middle and cut it along THAT line - I thought it meant the seam in the cookie. So I was very confused and like wow I must be experiencing a bug... nope.
However, I did have the problem mentioned below where sometimes my cookie pieces would bug out and I couldn't pick them up or attach them properly. It was not consistent and did not happen in every level, but in the ghostie level this really messed with me since there were so many pieces T_T
It'd also be really nice to have what the "par" was after every level instead of only if you beat it. I always enjoy that feature in such games.
But anyway, this was still fun and funny ^_^ Nice job! Thanks for making it.
