Hi!
Oh, nice, travelling is nice and dandy, hope you enjoy ! I too was/am planning to take part in the vimjam (theme is on the edge) and I have a working-ish prototype, it's some sort of platformer where I've already implemented a physics system, I only need to make it fun (which is hard lol), but I don't know if I will have energy/time left to finish it. I too am planning on travelling soon.
Other than that I'm planning on joining the ludum dare jam in begin October. I don't know which jams could be fun next, which is kinda unfortunate, do you know some ?
P.S. hope you had a great time travelling :)
