This is a pixel font, I think. Made in one size, drawn not with vector lines but pixel boxes.
they were rarely sold afaik, and very often custom made. A vast majority of the pixel fonts I collected didn't have names, but strings of numbers or similar identifiers.
they were relatively easy to design, and a lot of the charms of this one is its inconsistencies, see how E doesn't sit center in its space, for instance.
Given the visual sophiatication of the game, its very likely the developer made it custom for the game.
the font should, if this is true, be stored as a single bitmap image in the game files.
