I thought this game was amazing! you made a baking game that is actually like baking! Even waiting for the cookies to come out the oven was suspenseful and exciting. I know that you have limited time, but here are some ideas of things that you could add in the future.
Firstly, I think you need something happening when the cookies are baking, (I thought my game had crashed,) This could bee steam wafting from the oven, dialog saying the smell nice, or even a timer ticking down.
Maybe some different recipes would be cool, like cake or other cookies. You could be able to bake something again, instead of going to the home screen. Maybe you could earn points to get new recipes.
