I was hoping to be able to participate in LD16, and I’ll still try to get something in. Since I’m in the middle of a move, though, it’ll probably be something fairly small. That might be a good thing in any case, though, since my LD15 entry was too ambitious by far and suffered badly for it.
In any case, if I am able to participate, tools will be the same as in LD15; ruby, gosu, pixen, mercurial, and (hopefully) sfxr.
At the moment my computer is in a box, however, so prospects are somewhat dim; I don’t plan to set up a development environment on my girlfriend’s laptop (where I’m typing this), that would be rude.
