Fun, thought-provoking game.
I found this game to be one of the best 10 minute gaming experiences I've ever had. I thought the graphics and fonts were appropriate for this type of game, the colors you chose were aesthetically pleasing. The music/sfx were pretty upbeat and I thought they worked well to create a sense of optimism, though I probably would recommend making the music a little less optimistic as the game progresses just to fit with the 'obstacles' theme.
I liked the gameplay dynamic of having to pin one (or more) lover in order to reach the shared goal. I'm sure you could base another game on this dynamic alone and make a pretty entertaining game (though it wouldn't be as compelling). I also enjoyed the versatility of the inputs, maybe I'm overthinking it but it seemed like you were saying "Not trying to change who you are, pick the input that feels right for you." which works well with the moral of the game.
Other than the small criticism about the music, I can't find many negatives to the game. The only reason I didn't rate 5/5 is because I typically reserve a score like that to games that are not only awesome (which this is) but also offer a completely new take on gaming or required an immense amount of programming savvy. Consider yourself 'favorited'.
