MX Simulator

so I have recently switched to an arch based linux distro and I'm having issues with installing snapshots. I have been able to install the base game just fine but when I try to replace the mxbin file with the updated snapshot mxbin I just get a permission denied error and I don't know why. I have tried running "./mx" in the terminal with sudo and still got the same permission denied error. Any help on how to fix this would be greatly appreciated.

It needs execute permission. Try "chmod +x mxbin".

How did you install it on Arch? I'm new to Arch linux. I'm running Endeavouros. I have an idea of what to do but want to make sure I do it right.

Copy it over mxbin and give it execute permission with "chmod +x mxbin".
