I use Windows to make my games but i have heard that Windows files can be used by Linux operating systems through a program called Wine but having never used Linux before i'm not sure if my games should be Linux compatible through this restriction or if my games should remove compatiblity for Linux.
You must remove it. When someone sees that the game is compatible with linux, they expect it to run natively on linux, not wine.
Checking the linux compatible box could be considered cheating if you only have a windows executable (if I remember correctly, this is even said somewhere in the itch tutorials about quality)
Wine allows you to run applications created for windows, but depending on many factors, it may be simple or it may require many previous configurations in wine, even your game may not run or run with poor performance.
Also don't say it's compatible with wine unless you test it first, even proton which is an improved version created by Steam can't ensures that all games will run on linux.
Hechelion is right, but also: thanks for thinking of us Linux users. If you have the time and patience, you could try to set up a Linux VM and test your game in Wine. If it's compatible say so in the game description, it will be appreciated and you'll gain a few more players.
But please use another archive format, RAR is a pain in the behind to deal with. Thanks.
