First off, I just want to say that I'm very impressed with the app and intend to upgrade from the demo version in a few months when my financial situation should be a little better.
Secondly, the point of this post, is to ask if there is any particular reason why this app hasn't been listed on Side Quest. I was lucky enough to stumble upon it on itch, but I think it could reach a much wider audience if it were available directly on SideQuest.
