The current client for Polytoria is ubuntu linux and yes it is great but it won't work on some computers with debian linux
And .deb archives are easier to install
And i am struggling to install polytoria because my computer won't install it no matter what i do so i ask to atleast add a debian linux download so all people can play on linux

windows is free

last time i checked i needed a license to use windows

technically speaking you can install Windows and use for free. But legally when you install Windows you agree to Microsoft's terms and conditions and they state you must activate your copy of Windows, and that requires a license which must be purchased. So legally there is no free copy of Windows.

and polytoria would have more players if they released support for debian linux so yeah just saying
