This game has a "hold hands" button.
The prince & princess smile when holding hands.
Need I say more?

In case I do, great game. Cheap deaths were common for me in a few places, including after actual hard parts, but before the next checkpoint, sending me pretty far back at times. That, plus my personal feelings towards the ending, are what's keeping this otherwise great, adorable 2D puzzle game at a 4/5 for me.
