Each individual molecule did reach an excited state and entered the air, as the air molecules themselves are already highly excited. Also, if the air already has enough moisture then the moisture molecules in the air can accumulate on surfaces that are cold enough that they lose their excited state energy, and a puddle could remain even in warm temperatures because as water leaves the puddle more can also accumulate there.
This game has far too many mechanics. The dev team should prune it back to the essentials and focus on polish rather than getting over ambitious and not executing anything well
