I can't say there's much offical support for mobile as I'm developing this primarly around desktop but it should run okay in most mobile browsers, I know a good number of my users play the game on android just fine. I don't know what apk files involve, but I could look into it.
As for TFs, coincidentally I've actually implemented a hybrid, species mixing system in the latest supporter build. It dynamically calculates up the players mutations and assigns them a species based on it, some combinations of transformations have unique setups for those combinations. It'll be expanded upon over time as more TFs are added. Most of these on the chart aren't implemented just yet, so right now it can be mixes of: Nepharsi, Geckling, Kindred of Grease, Bovine Liminals, Porcine Liminals, Canine Liminals, Rodent Liminal, Berry-morph, Oojinn and Melapoid
Here's a screen cap of the new mutation table. More to come in the future ~
