That’s not a way to think when developing a game. You should assume that people will always change things and get things to their liking, even if you personally believe they won’t actually use the setting. + This sort of thing will prevent you from adding features in the near future because you never acted on it in the past. Punishing the player for opening the roblox menu is a terrible idea and kids will indeed get fed up. (it’s really easy to make a young person mad and leave cuz they lost all their progress)
I’m not implying you’re building a game that you want people to play, but I do recommend being in a mindset where you think about all exploitable things that can ruin your games, and patch them the best way you can, instead of taking the easy way out.
Nonetheless, you’re making a game that is dependent on a hardware cursor so at the end of the day if it does prove to be a near impossible project, at least you learnt a lot.
