I would recommend making a full version when the jam is over (like I will) because in stage 3, there is spawn kill (and unfortunately the rules say that you can't update the game while people are voting), even so, great 3D and music, graphics.
It's an endless game, and yes, since there were only 9 days to do it, time got the better of me, but I'll see if I can change it for the full version after the Jam.
