Oh! Were you wondering if you can create a game from scratch on the other days as well? The answer, is no. You can only work on other peoples games in the later days. You can create as many games as you want in the first day, but you must work on another person's game on any other day. If you were wondering if we can work on multiple people's games in one day, I would say not, as they will be expecting you to dedicate time to their game.
