This game was great. I'm surprised this is your first jam and have a feeling this is going to be one of the top games. Reminds me of the kind of game I might have found on Kongregate browsing the IF tag. The difference in perspective of the two characters was done really well, done to the colors. The guy being down, and getting more depressed, the girl being more positive and reassuring herself, until she starts to realize she misses him and she made some mistakes too.
I did have trouble with dying a bit at the beginning, partly just because I was still getting a feel for the game and partly because I sometimes hit Space to jump by instinct.
