Still need some more changes, but a good step in the right direction! Make sure to revert your changes to the .csproj!

Looks good, I'll test it myself soon, idk if Yamato wants to get rid of that weird delta in the csproj but I personally don't care

I think it should be tested cuz I don't really remember but I suppose we can't cast ICommandSender to Player
