Hi, posting this both to Community.gamedev.tv and to the Q&A section on Udemy just incase :).
After messing about with the camera and changing the Field of View and then exporting a build of the game, I noticed, it was cut off at the sides, in some severe ways. The resolution being set to “free aspect” doesn’t help when designing a game like this where it doesn’t account for different resolutions.
So I’d suggest a section that shows how to set the resolution (Game panel -> where it says free aspect -> click plus symbol and put it in there) and put in 960x600 (the WebGL resolution) so people can make sure everything is perfectly fine before building the game.
