Saw the game on Discord and was curious of the final result. Amazing! Crazy that this is built in Scratch and even cooler that you provide the project file (interesting choice having one mega sprite). Great job!

Having one sprite handle everything is key for big projects, since you can have a core loop that while not working at a steady framerate still keeps functions from "running on top of each other". It's basically PICO-8's _init _update and _draw functions, and since I'm erasing and drawing the graphics with Pen every frame, nothing from another sprite would be able to "cooperate". There is one other sprite that is stuck to the middle and full of a screen-shaped window of 0x00000001 glass. This is "shown" but you never see it and was a simple way to not draw items if they don't touch the pane.
