Thanks! The first level was to show the basics of the gameplay loop which included finding a key to put into the machine to turn it off. I probably should've put a message saying you needed a key to turn off the freezer for the remaining levels. I will be looking into ways to load the game before hand because this was never a problem I had to think about for making 2D games with Godot but with 3D it would make sense since the amount of data that even a single 3D model stores no matter how small contains a lot more than the most detailed 2D image. Thanks for the feedback!
