Honestly, I do not get why InnerSloth has not fixed these issues yet. Among Us was the most popular game just a few months ago, and still they did not have the sane mind of fixing these. I mean, the teleportation hack is very easy to fix. All they have to do is make player movement server-sided and implement client-side prediction. Even I, who has spent barely a year and a half in Unity was able to create a game with client side prediction. And my game was 3D. Other hacks are easy to fix as well. Make the purchase check server-sided (ok I'll admit this one is a bit harder to do, but nothing for experienced programmers), make the kill cooldown and other cooldowns server-sided, and a lot more which my small brain can't think of.
