Brainstorm Board After we get the topic of this week's Game Jam, we started to brainstorm ideas on the whiteboard, consisting of everything, game-related or nongame-related. these are some sample ideas: the paper roll that the start and the end is one point Mobius belt the mirrored world that two sides end up together player level up and at some point, the player has to defeat him/herself (the stronger, the more difficult) the natural circulation: rainwater - river - sea - steam - cloud - rain rolling the cube at the grid space ends at some point at the state of the begin the HP and stats of the player have to remain the same at end and start one single line draw of a vector line from having to not having to having - circulation the life thread of people - someone becomes together and someone will be apart, you start your life single and end your life single the time to back - maybe 5 secs elapsed and 4 secs recovered; every 5 seconds player will be the pace 4 seconds ago etc
