Got on with my new project for this jam today, having well and truly discarded the visual novel. I can't quite figure out exactly what sort of game it's going to end up being, I'm building it out based on a general feel I'd like it to have rather than based on systems I've designed. We'll see how that goes.
Already learned more in the last two days than I did in a week and a half working in Ren'Py. Although I am glad I tried it, and gained a passing familiarity with Python. You never know when that might come in handy.
