So we decided to go with a 3D runner. The themes we chose were Castles and Chain Reaction. The runner runs on the dominoes trying not to fall and tries to destroy the domino castles. The castles can be destroyed by falling the right dominoes, or if you make the wrong ones fall you may doom yourself, so it's also a puzzle, but with no time, and the rush while trying to stay on the dominoes who can really put the time to find the best path. So it's gonna be a difficult one, so get ready for some frustration. 
What we got to do today was to make the first level of the game, which is kind of a tutorial, a simple one which I myself can't play (don't judge me). We also got the physics to work and the runner can actually jump, but it's way too difficult, if you don't believe me watch the video (if it's uploaded), our artists also made a cool domino model, which looks amazing. That's almost all we got to do today, coming up with game play took a lot of our time today, so expect more progress tomorrow.
First level with physics:
A little bit of game play:
Interesting.
But I can forsee myself getting a bit frustrated if I got most of the way through and then fell off if it took me multiple attempts like in the gameplay video.
If I may offer a suggestion: Increase the jump height and or the air control to make it easier to land on the dominos.
