Step 1: Have a team and outline your roles before you start so you don't trip over each other in the short window you have.
Step 2: Give up sleeping, you can do that when your dead!
Step 3: Be retired and spend all available hours on it.
Step 4: Use asset packs and lots of prefabs!
It was a really fun project and I think our team produced a pretty great product. We have already discussed going back after the jam and fixing up some of the bugs that are present and overall just clean it up with some extra time and care. Thank you for taking the time to play, comment and hopefully vote. Feel free to find me on discord ;)
