1. I made this game because I wanted to play such a game :-)
2. I'm using Java as the programming language with libgdx as the graphics library and a number of my own libraries. libgdx is plain awesome for an experienced developer like me.
3. I'm doing this game on my free time but I'm a professional developer!
4. This is very kind of you but I'm not looking for development support. I'm looking for support 1/ for translations (besides German, Italian, and French; for which I have translators already) 2/ maybe for pixelart in the near future, and 3/ for advertisement (but you did a lot commenting here already ;-)
