Thanks! I don't know of anything exactly like that, but there are plenty of hackathons and the like that are similar. It's not to hard to sit down with the docs and/or tutorials for systems like Godot, Inform 7, Ren'Py, etc. and put something basic together. Expect to throw away your initial one or two projects, but after that you should be good to go. I built Minima & Anteform using PICO-8, a virtual console. The RPG game system they use I had to build from scratch first. For me it was mostly a challenge to see if I could fit that much gameplay and story into the available footprint, but if you're starting out with one of the systems I mentioned it should be a lot easier. Also, don't get discouraged if you seem to be "almost done" for a long time. It often takes as long (or longer) for the last 10% and polish than it does for the initial 90%.
