Are you afraid of judgement? You remind me of a friend of mine who was ashamed of her own paintings, and didn't want anyone to see them: but indeed they were beautiful.
No, I'm fine with judgement.
I'm just not happy accepting money for something I consider sub-par, and I don't want to give away for free something I once sold, devaluing the trust and support of my customers.
I make plenty of free games (I should upload more to Itch.io, but I don't have the time), and I'm working on some commercial projects, they'll be up when I feel happy accepting money for them.
