Oh, but your friends don’t have to be game devs to be able to participate. They can be artists, writers, composers… that’s the cool think about videogames! You can also try to find people participating in the jam if you ever want to work with other people in the future. Based on the screenshots though, the game you made looks great! I am all for voxel art. I don’t know if I’ll have much time to try it out, but I hope I do!
PD: I, too, met myself when I was born. Perhaps even sooner, when my brain developed! :p
