Definitely found this interesting as a concept - the donut mini game went wrong on me at one point and started going crazy no matter what I did (O and X appearing at the same time and all sorts of things!) The jam/glazed roll mini game was fine until I had to roll it and I could never seem to get the mouse in the right place!
The coffee game and pretzel games worked fine all the time though.
Like the concept, good Jam game!
