I always love when a game tells me not to play it. Great experience, it has made me think!
PS: Just one thing. I like to play the games on window mode (specially on this jam), and I have a bit of problems controlling it, as it has a first person control, when you put the mouse off the window and pressed a button to shoot, most of the times i lost the focus on the game.
In unity, if I'm not wrong, you can use it to avoid this:
Cursor.lockState = CursorLockMode.Confined;
And again, great entry!
