When we started developing the game for LD59, we had 2 programmers, me and one more guy. The guy was busy a little in the beginning, we invited him hoping he will help us after some time, but he started ignoring the entire team after a day. I continued programming solo since we understood he will not help us, and it was a mess. I burned out a little, barely managing to code the game fully, even though our team had to remove some aspects of the game. In the future Game Jams we definitely won't invite strangers, we will work with those we know. You can check the result game in my profile.
