This is just a batch file that has instructions to run the Batch file, run the game in steam, then press x to enable mod. This seems sus to me, bro.
As a cyber security guy, I super super apprecieate the call out (more people need to talk about batch file vulnerabilities, honestly). Not sus, more so we uploaded the wrong game files just before the deadline, gotta wait for the jam to finish before we can fix that
OOF! That has happened to me too. I sympathize!
