Whereas the CPU requirements are actually very low. And with some little sponsoring, this could also come to a full completion, leading to a mind-blowing product in little time. And also produce spin-offs like something similar, but written in C++, and featuring nice, textured OpenGL graphics, and even lower system requirements ; and even more... . Brought to You by Simon (alias ''the Nerd of Algorithms") If You thing You think You may become a sponsor for it's dev, let me know.
