I still need to make a big post about this, but we had tons of new players starting 12/15 which took down our servers for four days. I worked 12-hour days trying to fix it until yesterday. Now the server is much better, but there may still be some other issues less frequently.
Also, yes. Because itch has poor support for DLC like our hats (but we still love it here), the PC version is 5 dollars everywhere.
