This is such a cool concept, and really on-theme! I would have liked to see more story - telling us what the characters were going through in their joint lives, or how they feel about being tied to each others lives this way would have provided a really interesting new dimension to the game.
I really enjoyed the gameplay - it was great fun figuring out how to get past the obstacles, although like a lot of others I really struggled with the spikes and could've used a save point, or the opportunity to practice getting past them earlier on.
AND THE GRAPHICS - amazing! I was watching your progress on the Discord and wondering what kind of game you were making. The end result is fantastic! The music was also on point.
