Very good concept there, and nice art too!
You could have assigned other button for player 2, because it would be easier to play in the same keyboard (or assign something like space bar for p1 and mouse click for p2).
Thanks for playing and your kind feedback! Having the players share input was an experiment to see how it would affect the experience extrinsic to the game itself. Would players sabotage, push each other around, cheat? I thought it would be interesting to see how that worked when under time pressure.
If I wasn't purposely testing that, I totally agree with you that it would've made it easier to play.
