Thanks for pointing that out. The game does check all of the ingredients but right now it just checks each ingredient to see if it's on the ingredient list, so you could succeed by using any combination of the correct ingredients (2 pizza, 2 bagels, etc). I'll have to fix that after the jam.
The audio bug is annoying and I unfortunately didn't realize it until too late because I was playtesting the game with speakers instead of headphones. Turns out that it's a "feature" related to Gamemaker 2.3's new sequences system where the audio object plays sound in stereo depending on it's x,y location in the game room (at a massive biase apparently). This is an easy fix but I'll have to wait til the jam judging is over.
Thanks for taking the time to submit bugs!
