After a little research and programming I am now able to use Ren'py for my project. Taka can walk and the screen will follow him. So, Adventure styled point & click game - Let's go. ^^
As soon as the script gets some updates I will post it, so that other may use it.
I'm currently working on some bgs. I used blender and overpainted my renderings a bit with PS. Textures were done with PS and Sai. The graffiti was so much fun *__* and other will added.
