How to beat the game
Escape as Minnie: Choose Diabeto, Run (or keep attacking) through the eclair, collect enough candies from the packet to defeat it, then collect just enough candies (attack the packet after its dead) to explode near the Cake right after eating the pudding. Minnie can just walk through now.
Escape as Diabeto: Choose Minnie, and harden literally anywhere. Your choice. Then throw her hardened body at the enemies to instantly kill them. If you want to kill the candy packet using her, wait till her sugar goes to zero, being idle is the fastest way to lower her sugar.
