Ahoy hoy!
I’d like to make a suggestion, which is a small one but could have big implications. I’d like to suggest setting up the Android app to be available/compatible in the Chrome Web Store. This would give access to the game to a more expanded market, as it would be possible to play it regardless of platform. For those unaware, Chrome on all platforms now support Android apps that have added compatibility, and from my understanding/what I have read, getting an app compatible is very mild on the difficulty side of things.
This would open up your market to not just PC (with the steam app) and mobile, but would also allow people on PC, Macs, & even Chromebooks/Chrome OS to play the game. Also, being as the Facebook syncing is in the Android version, it would also help resolve the lack of facebook syncing in the Steam version.
Thoughts?
