I thoroughly enjoyed the concept behind this games character. I think it's a super unique idea and one that you should really consider expanding. This was mentioned in class but at the conclusion of the game one of the players ends up being, for lack of a better word, "deleted". And it would be interesting to see different ways to handle that, such as making the player on the back fold into the first player so it feels like they've come together to make a stronger protagonist. One thing that you could do is have the player on the left of the screen ( which I assume represents the struggles that character has gone through ) stronger. Maybe this would allow that side of the character to move an obstacle out of the way that the other side can not. Perhaps there could also be a flip function where the players keep the same side of the actual character and its attributes, but they which swap side of the screen they're controlling. I think it would also be cool to add more of those animations that were mentioned where one side of the character is mounted more on the back. Anyway love this idea, hope you get to expand upon it!
