Thanks for the feedback!
The planet was built procedurally in Unity, with superimposed layers of noise used to offset a spherical mesh. The basis of the editor for it is from Sebastian Lague's tutorials on YouTube on procedural planet generation. All of his stuff is amazing, you should check it out :) https://www.youtube.com/user/Cercopithecan I did try to give him credit in my game page but unfortunately that description doesn't seem to carry over to this page! :/
Yeah it can certainly get out of hand quite quickly :) I'll have a look at how to make music for the next one or maybe add it to this one after the jam.
Cheers
