I just uploaded a very small fix, which might interest you. 

When you previously uploaded your games to itch.io, they were not playable on mobile. The reason being that itch.io flipped the game to landscape mode, which made the mobile controls invisible. I found a way to prevent this, so if you create a new game now, it will also be playable on mobile devices. (except iphones, because other problems occur 🙁)

I also recommend to import and export your old games and re-upload them to itch.io to make them available on more devices, therefore this post 🙂
