These game jams are always really difficult to scope to be honest. I usually try to build out whatever feels like a core feature that has just enough play time (5 minutes) before tackling the art and then other aspects. I think it's always a fun challenge to work within the limitations because it pushes us to move rapidly and test us :D

That's a really good way to go around the short time frame! I'm only the artist of this team and sometimes we get too absorbed to our own areas. It's gotten to a point where once i didn't even know what type of game i was drawing for :O Following your strategy, i think i'm gonna help flesh out and test the core features more the next time before making the visuals better :D And yea, game jams are really amazing for learning a lot of things in a short while!
