Interesting concept but unfortunately I wasn't able to experience it as designed.
I was evading the falling sweets and getting the hirosontally moving cakes. I noticed that the cakes give health when health < 3 but confusingly they also took it away when health === 3.
I hit a bug where when I am right next to the edge of the screen and there is a cake which comes the game loops and sends infinite cakes. Which allowed me to confirm the observation above.
The game only triggered the rainbow eggs mini game.
I will wait for your update after the jam to play the whole game.
Good luck!
