I have looked at enabling the virtual keyboard for the Android version. Unfortunately this requires some changes to the rendering (caused by the a settings in the manifest) that would require more time for me to figure out. I much rather spend the time I have in improving the game it self.
Sorry if this is disappointing to you...
I'll promise to let you know when I do more updates to the Android version.
At least it got me thinking.... and I think I'll implement a custom keyboard ingame.
