This game is hilarious!
I enjoyed playing and "studying". It took a bit of figuring out the controls but it was worth it.
Use of theme is nice.
The only one thing I noticed is that some of the icons are broken and Unicode is showing. Maybe exporting them as images would work better.
Also, the pixel art and limited colour palette makes it difficult to "read" what object you are interacting with.
Also, the pixel font could've been a bit legible. e.g. https://fonts.google.com/specimen/Pixelify+Sans
