Thanks! Only one question...what is "playdate"? XD
Anyway, i developed this game with Unity 2019 and i builted a custom script to just move the snake around the sphere. All the other stuff is just well placed elements and some 3D modelling...
Oh it looks awesome! Unfortunately i can't affor the Devkit so it's a little bit off range for me...but it looks a very interesting device! If i could i would develop on it!
