Imma be honest, i cannot upgrade the base/village if it has been implemented already and I'm still sad that I can't play more of it, but please continue on developing this game, it's one of the very few i enjoy mainly for the plot.
There seems to be a problem with the graphics on the android version. Almost everything is either cut off in half or it's replaced by a different image. I am btw using JoiPlay to run the game.
