After somebody suggested this in the comments of this blog, I thought about creating a 3D version of Darkness Springs. Maybe this would be fun, and it also would be quite easy with the flash 3D engine of Coppercube. So I sat down and tried to create a small test:
This was just a small test (the enemies are not moving and not dying), but it seems to be fast enough to be playable. So should I have some time in the near future and don't know anything better to do, I might start creating a 3D version of the RPG, would be fun.
