The character art is good, but the gameplay is way too frustrating to put up with to see more of it.
Everything is way too floaty and slippery; could just make it right click to flip or something and reduce how far things slide around by like at least half.
Doing orders perfectly and on time but not getting S ranks because of invisible metrics; cooking, stacking order and time are plenty to grade on, you really don't need anything else.
Losing entire burgers when you switch screens even when they're on the plate, I guess because the game left it floating half a pixel too high; maybe make the 'safe zone' extend all the way up the screen, if there's some issue preventing you from just not deleting stuff that isn't on the plate.
