Finally! 
Graffitown’s game engine is in alpha phase.
The environment will be redesigned soon while the GUI design is more or less ready. Some important features are still missing, but they are in the pipeline.
Group membership guarantees some extra features for the players (and more will come later), feel free to join to Apafey Studio group!
Gamepass for early birds is available in the alpha version on a discounted price and it remains valid without any time limit. The final price is proposed to be 79R$ in the final game.
I hope the game can work quite stable on a public server / multiplayer environment, I would be more than happy if you could test is and share your experiences with me.
