The idea of ​​the story One atom of the almighty God

The idea is that the protagonist gains the ability to do anything, but it's absurdly small. Instead of a fireball, there's a flash a tenth of what happens when a match is lit. Teleport 0.5 cm, travel through time for half a second. Anything, but it's very small, fully functional, and doesn't scale. Like, a teleport is a teleport, not a fast move, and you can't use a million teleports per second. But it's a full-fledged teleport, without nasty debuffs like getting stuck in textures.
