This should have multiplayer
It would be fun to play this game with my girlfriend because it's not too hard of a game (the simple controls means it can support more than one person per keyboard) and it subtly tells a very loving and passionate story while still being fun and not inappropriate. You might even make it so at parts its the too people at the same time and at others maybe they broke up and other people are involved so the idea of switching still works, and maybe opens up the idea of up to four people on one computer, each controlling two people!? Yeah, that all might be a bit much, but I'd love to see a sequel, great job!
