itch.io should implement tipping, TBH, because sometimes those free/$1/$2/$5 games really do deserve a $10 tip, you just don't realize it until after you've played. The difference being that you know you're tipping a tiny team, usually only one person, almost directly, instead of an amorphous husk that just laid off 20 employees after the game.
Oh, for sure. I'm not against tipping in general. I used a lot of Cities:Skylines mods and I always send a tip to the creators of my favorite assets and mods.
