if by 'only game' you mean you made it all by yourself... Just to let you know, I made cool guy teaches math all just me... I know I have to other people helping me in other projects, but CGTM was just a me project :).
By 'only game', I did mean myself, but I also meant it's the one game I've put on itch
Oh, it's still a good game though :). Keep up the good work!
