Sounds like a good start, got plenty of time to expand and improve, and yes, playtesting is very important, something I to forget to do sometimes, when I do game jams.
Possibly. It depends on the number of entries and if I get the time, but I would like to.
Also not sure how to structure the videos, be it me playing them with commentary (which I'd rather not) or find someone else to do that, and i'll upload it, or something different entirely, suggestions would be good!
