Hello, Thanks for playing!
I don't think so that I will do more with this particular project, however I will be releasing new ones in the future, and I hope for them to be longer ones.
Next step I think will be learning how to do rigging and animations to create 3D enemies and learning how to implement weapons into the game, so next one should be more FPS like, however I don't know if I won't release something like "Blending Shapes" in the mean-time, because I really do enjoy creating environments.
Have a good one
