Hi, I'm currently developing a game that wants to do something similar. Mostly because of optimization purposes, so I wanted to try the demo to know how much better it did compare to a 3d game in a Mac, but I'm not sure how I'm supposed to launch the game.
I opened the .gmz file with the program TheUnarchiver, and got a folder with gmx files and other games files, so I'm sure I did something wrong, but not sure how to solve it though. Could anyone pls help me?
