Currently I have running jumping and attacking physics for the ninja. 5 complete enemies, and some textures and graphics.
By the end I want to have three game modes. (endless survive, endless waves-protect the dojo, and story mode) A level select system like gravity hop, a complete menu, different music for different themes, (normal, ice, lava, defend the dojo) and a story!
I'll update this discussion whenever I make a significant update.
