Hi there! First of all thank you for providing me your thoughts about what you think. It's very important for me and the only way I can improve the game and myself has a game developer.
For the buildings I thought about that and I notice it. I must give them some sort of perspective to getting it out from the background and play with the layers to find some solution.
Sorry about the keyboard thing! I use the space key for the pause menu and dumb enough to forget keys to replace the mouse clicks....
During the week I will work on that!
Thank you!
