Funny and perky game, good job! The graphics are personal and lively and the music fits the game. Sadly I wasn't able to test 2 player game right now but I can imagine this would be fun with two human players.
My favorite minigames were feed the sumo, equeerstrian, nudist javelin and pill maze. Also table tennis was a successful and stylish interpretation of Pong. I didn't enjoy that much the race and the hobo hurdles. This was mainly because of the randomness. Randomness is a good thing but I think it should be constrained a little so that in the race vegetables and drugs don't appear too close to each other and in hobo hurdles obstacles don't appear all the same time making them quite impossible to avoid. There were couple times I felt like I was doing the best I can but I got bad luck and thus failed.
Anyway I guess I have to invite my friend over to play some Olympdics
