i got a bit lost in the controls but once i figured it out i still got lost. I did understand what it's trying to be, but it's a bit lacking in gameplay. i can't really get over 4 points before getting a game over because the food doesn't spawn before the kid gets angry. I also don't have any control on when it spawns, so it leads to a ton of cases of me waiting on the table for the food to spawn, it doesn't and game over.
The pixel art is nice tho and the idea is really good! Maybe with a little bit of time it can be pretty fun to play! In the desc you said you want to flesh this out into the entire pizzaria, so let me tell you it's got a ton of potential! I just needed to point this issue out so it doesn't get unnoticed.
