Can you use Toppling spell with Hungry Darkness?

[TLO3]

Hungry Darkness: 60 ft of deeper darkness 3d6 force and 2 con damage plus 1d6 bleed after leaving area of effect.

Can you apply toppling to this spell? It's a force spell that does damage, I'm just not sure if the wording of toppling spell means it only works on targetted spells or not.

Toppling Spell (Metamagic)
Your spells with the force descriptor knock the affected creatures prone.

Benefit: The impact of your force spell is strong enough to knock the target prone. If the target takes damage, fails its saving throw, or is moved by your force spell, make a trip check against the target, using your caster level plus your casting ability score bonus (Wisdom for clerics, Intelligence for wizards, and so on). This does not provoke an attack of opportunity. If the check fails, the target cannot attempt to trip you or the force effect in response.

Its got the Force descriptor, so yeah, why not.

[Falcar]

Yes because the target takes damage from the spell. Think of it as the darkness pulses within itself harming creatures and knocking them to the ground. It does not say i has to be a target spell.

That's what I was hoping, but was worried that since it's an area spell with no actual targets that it might not work RAW.

I really like flavor of this combo, even if it is fairly weak for an 8th level spell slot.
