i forgot to tell you guys that my platform game is finished, it has now 3 castles with 12 levels each and also include 3 boss fights.
it was a though project but i am happy i started it. now i am working on an android app (real nice tool).
but i really hope to see more libgdx box2d games from guys here in this forum. i will definitely make more in the future but now i will concentrate on different projects like tools and multiplayer games.
