Thanks. I'm happy you liked it so much. We'll see what happens regarding the further development if enough people like it.
The initial idea was that it plays on a globe, but had to turn it into a makeshift 2d thing to save time. Most of the jam time was allocated for prototyping the core mechanics. Graphics were kept super simple for that reason.
Making a spherical version with flashier graphics is definitely something I'd consider doing... in the future :)
