Well, first of all thank you really much for your feedback and kind words. As you hopefully can see in the devlogs stones, bushes and one of the snowman (the ice one) is now implemented. The game that is shown in the video is done in unity, but not by me but a friend. He made an package wich now is also downloadable.
The particles in the screenshots are animations so the snow from there would probably be hard to implement.
But I’ll try out your BB-8 Idea, it is sounding really good :)
