First of all, sorry for the delayed response! Thank you for the compliments! We are trying to improve the game more and more! There is a huge amount of empty space at the moment, but with each update, we are bringing more life to these spaces with new characters. Unfortunately, as the game is not yet our main job, we can't dedicate as much time as we'd like to release updates faster, but slowly we're putting things in place, mainly with the help of community suggestions. Art then is an exciting point! Our artist didn't have much experience at first, but with each day she is striving to improve more and more! =D Anyway, thanks, and I hope you like the news we will bring you soon.
