Hello Ethael!
Welcome to the PawByte Community!
To answer your questions,
1.) The short answer is Yes.
At the moment, we are currently focused on improvements with the C++ support side of the engine. Android support is still very much in it's infancy, so plans may change. Initial Android support most likely won't be ready until at least version 1.3.2+ or higher (based on current projections in February 2018). Since APKs need to be signed before installing, we will need to sign the generated APK regardless. Currently, we don't have plans for managing a jks keystore, so you'll need to generate your own and provide it to the engine. (This isn't too bad with the keytool utility.)
2.) Again, Android support is very much in it's infancy. Touch events is currently not supported in the current version of GPE(1.2.1-RC). However, it will be implemented when mobile support is released. Current documentation on the supported game input methods are located here, if you are interested: http://docs.pawbyte.com/game-input/
Last thing I'd like to note, is that Game Pencil Engine is an open-source project, so if you or anyone you know would like to add to the codebase and accelerate development on things like mobile support, we'd love to see the contributions.
Hopefully that answers your questions. Let us know if you have any other questions. 😄
