This is an elegant twist on the Lasers & Feelings formula, and gives it just enough extra 'game' to mix things up.
I particularly like the Keepsake mechanics -- both for awarding them and the fact that you need to spend -all- of them to clear Heat -- and the Emotional Encounters table, which gives me EXACTLY the vibes I want from a game like this.
Honorable mentions to the mech 'sketches' with the snail tank.
