Rectangular cakes can spawn horizontally or vertically, to reach wide or tall. Donuts are always round enough to roll away, so keep an eye on where they might end up. Square cookies are sturdy, but can block the way if you use too many.
Collect enough sweets on each level to pass to the next one. OR try again for a new high score. Sounds sweet, right? Don't be afraid to try again - there's a restart button there for a reason. Sometimes, just like in real life, a bun is a too bouncy or a swiss roll is too springy. But don't cry over spilt milk! (Because virtual cake can easily be made dairy-free!)
