I personally avoided this whole high school thing by dropping out but heard about it through others. It's a bit tragic but you ended up making a fine ass game. Here are some things you could have done better (in the game):
The color scheme and general palette was very disorienting, if that was the vibe you were trying to shoot for you nailed it.
The font was not accurately displayed in the game. You need to change the font settings. I'm a Godot Dev and you just learn it by playing around with random things in-engine and hovering / going to docs when you need extra help. (hold Ctrl and click on a method to get it's documentation!)
That's pretty much it. I could really feel the suffering through the music, visuals, and Gameplay. The little voice in your head thing was especially heartbreaking and a fantastic way to storytell. 8/10
Post-Script: The art was actually really nice
