Hey, looks like there is another missing shader compilation check.
The only reason this would happen is if your computer can't compile the shader so I guess your computer does not support it or something.
You're going to have to wait until I update the game, sorry about that. I'll try to get that done as soon as possible. (hopefully today)
I'm using GameMaker: Studio 1.4 to create the game.
Anyway, hope you enjoy the game once you get it running. :)
Edit: The game has been updated.
