Please don’t do this. Lethal company is a great game and anyone who wants to experience it should buy it and support the developer. Also the voice chat mechanics are a huge part of lethal company and will not work with Roblox. Sorry.
I understand your concern, but there is no universe in which my game will "harm" Lethal Company's playerbase. I'm also not making a direct rip-off, i'm adding my own ideas and features into it
