Function (game;) not starting

Hi there,

I have been developing a controller that has a 20x4 LCD on it, and I have been trying to integrate a game I developed in another file. I've pretty much just copy-pasted the values and bytes for characters and borders from the game into the controller code, and then turned the loop(); from the game into a function on the controller. I called the function "game," and it should work. The thing is, whenever I try to call it, it just won't run. I presume there may be something else in the code that may be stopping it from running, but I can't seem to find it.

To clarify, the code should configure the controller as a Bluetooth controller, until one of the buttons is pressed. Then, it starts the game.

Any help would be appreciated.

You're not calling game there

Oh, I forgot the brackets! Thank you so much for finding that
