It’s a bad habit, to revolve your world around a single person. Desperation and lack of self-confidence is hella unattractive, in any type of relationship.

A mistake that I luckily did not make, ever, not once.

True, can’t think of how would you combat a cleverly written aim-bot.

Don’t tell the client what’s going on outside its vision, I suppose? Add a small buffer to compensate for latency, so wall hack would be more of a “corner hack”.

I imagine the alternative way to combat kernel-level cheats would be asking player for all his game state data, validating it on a server?

Wouldn’t work on peer-to-peer and you’d have to do a bunch of unnecessary compute(recalculating every tick if player-generated data is possible according to game rules) but its the only way I can think of.

I mean, its free no-authentication VMs. They had to put at least some guards against abuse.
