It's so much fun to be a sphere and roll through a vast 3D space!

I also liked that the next building wasn't always immediately reachable!

It was unimaginable how much fun it was to roll through the desert with a bit of anxiety, not knowing if the building in the distance was really our destination, and finally arriving at a building that turned out to be a very fun athletic facility!


Loved watching having fun rolling and jumping around. It also made me very happy to see you being so fast with the last building. Thanks for playing and making such a fun video! 

Ah nice you finally released it - congrats! :D

Thanks you Maik! It has been time to finish it :D

Gamepad support?

I tried it but the following camera code is sadly against that idea. But never say never  


wow, very polished!



Fun little game with a unique movement mechanic and some gorgeous colored dunes! Very relaxing at first, but with a finicky challenge at the end

Thank you Tea for playing and making it until the end
