Alright, I’m sure we can consider using other effects. It’s not like we’re making any final decisions here. I just think DoF is an option we shouldn’t rule out from the get-go.
Two other games which adequately portray a tiny scale from what I can tell from looking at footage are Drunk on Nectar and Insect Worlds.

Insect Worlds on Steam
Drunk on Nectar doesn’t seem to have DoF while Insect World does. From what I can tell the system requirements are similar, but that might be because Drunk on Nectar arguably looks overall prettier than Insect Worlds.
Note that all three of these games don’t really portray a microcopic scale, but rather the scale of bugs which are about 1-3cm big.
