Hey, sorry for the somewhat late reply.
Good to hear that you got it running at least.
I'll add these parameters to my to-do list and then maybe include them in the readme file for the next version.
I'm going to have to look them up and see what they actually do first though, the first one is self explanatory but the rest, not so much, "vs,ps" is probably vertex and pixel shader but other than that no idea.
Regarding gamepad support, I have the exact same issue, no idea what the problem is so for now gamepads are unsupported.
I'm guessing the issue is likely because I'm using GMS 1.4 and the runner (the executable) is pre-compiled and from 2016.
I have plans to port the game over to GMS 2 which *should* solve most if not all issues but this won't happen until after the game has been completed.
So for now the Linux version is what it is, thanks for the feedback and posting possible solutions. :)
