Hi, unfortunately Babylirious has never been available on mobile, you may have played one of the many clones that people have made without our consent.
Itch.io can be visited via any web browser and purchases can be made regardless of the platform you are on. Just like how you can buy a game via your phone for Steam or even a console.
We don't have a release date yet for the next BiY update, but we will make an announcement soon(tm). We usually announce first on Discord, so come and join the conversation there!
Thanks for the support, and for playing!
