The big plus of a 2 people team is tight communication, like sharing one brain.
But work takes time, like creating co-op after single player is finished while tweaking the UI and subtle behaviors that no-one will notice, or doing lighting and uv and texture after the models and animations are done, oh and making a web site for the game, and writing down what the game is all about. It's like dumping brain content and present it all nicely.
It won't be too much longer before the web site is up and, in the meantime, we posted one of the scientific papers describing the weird ecosystem of planet M.
Until next time, have fun :-)
