Insane concept. Can't wait to dig into this!
I played this back in beta (maybe 6 months ago) ! Incredible game, haven't tried this new version but extremely excited to. Edit-- played it a bit today. Really really tight! Excellent stuff.
I backed this on their IndieGogo and have some credits waiting for me... The game seems to run really well, but like most new languages, really need to spend a day playing with the Documentation before getting started.
