The controls work well, and the game looks good too. The idea, while not revolutionary, is still a nice change of pace. The fact that the two characters are controlled oppositely adds an additional challenge every time you switch characters.
If I may give a tip: currently, players essentially follow the same path with both characters. It would be interesting if they had to take different paths or position both characters in a way that they can only reach the goal together.
But aside from that, it already feels like a polished game.
