Hi, thanks you for commenting, I'm happy you enjoyed our game! Both sides are correct, they just have to match, but the right side have to be mirrored. Sometime is more convenient to move a player rather than another, sometime you're forced to move one of the two player, paying attention to the edges so as not to block objects. We know gameplay can be a bit unintuitive at the start, due to the lack of an interactive tutorial. We just put a simpler one in the menu, because we couldn't have been there in time to create a dynamic one, but maybe we'll update the game to make it easier to understand.
