I did no such thing, the problem with the game is a problem common to various MacOS apps, or nix* executables for the matter, there is no permission to run the executable, which is why it doesn't work.
The commands I provided do three simple things, since the `.app` is a folder containing a variety of files, I guided you to reach the executable, then I gave you the command to give it permission to run.
You can Google them, it's what they do `cd` is change directory, and changes the directory. `chmod` changed files permissions and with `chmod +x [filename]` you give a file permission to be run.
In case the command fails since you do not have the permission to run use `sudo` to run the command as root temporarily.
It worked for others, if it didn't work for you it is either because YOU FAILED to follow very simple and basic instructions which explained 3 times with even screenshots, or it is because of another problem.
Since I'm not the developer of this game but simply someone that knew how to fix this and saw that many people don't, I decided to go and tell everybody how to go and run this game, there is even a screenshot with the game running.
If you still cannot open the game after that... well, it's kinda your problem, go crying to the developer about it, but do not call me a liar, because I am not.
