I have played this type of mini game many times before, typically in some food app where you can earn a discount if you score at least 100 points. The difference being, in the food app, it is designed for everyone to succeed, whereas your game is much more challenging - and thereby fun.
Your game is well executed and enjoyable to play. It creates a nice rush when the game and music increases in speed, and a funny "oops" moment when you get tricked into eating the discolored cookies.
I am not sure if jumping makes any sense in this game, especially at the later stages. I never used it, at least.
The pixelated menu graphics are also awesome. Well done overall!
