LightsOut!Medic

This is my submission for Godot Wild Jam 30!

The Theme is Heartbeat and I've chosen to work with the See No Evil Wildcard!
It has no visuals whatsoever, so turn the volume up!

You'll be guided by your professor through your last test on Medical College.
Listen carefully to the instructions on what and when to do!

This is my first Jam and my first game.
Constructive criticism is welcome and appreciated!
I've added a 10-second delay to start the game because the audio was shattering (maybe because the game was being loaded) on the game's Public Page.
Also, you'll need to click on the game window (the black screen), to make sure you're focusing the game. (To make sure you are, spam F: if the Doctor doesn't react, you're not.)

No patients were hurt during the development of the game.
