Been working on a game idea now for about two hours and we have come up with one, which actually took us a lot less time than our previous game. Here is how our design board is looking now:

Decided to go for a more unique idea of a game, not just your average plat-former, or fighting game - More of a puzzle game with an unique twist.

Will update when there is some game-play, until then, happy game-jamming.
