Hey! Similar concept to what I had! I love these kinds of games :) at first i didnt realize i had burned the meat and it wouldnt make a burger. i was on a darker screen so i couldnt see the stages of cooked. so a visual indicator might help for that.
once i realized that i was able to play through but it wasnt clear what the goal was. serve burgers for 1 minute? forever? so i ended it on my own after 5 servings. this flow is good, there might be more for this game! good work :)
