Dumb game idea time?

A dark souls like game where you play as Sukuna (she's about the size of a mouse) where you use ordinary arts and crafts tools as weapons (her main weapon is a sewing needle in the actual cannon so it would be thematic) to fend off ordinary and perhaps some supernatural creatures. 

The main goal in terms of the aesthetics would to give a sense of grandiose to every day items due to her size, so a perspective shift of sorts. 

Broken China could be used as a sheild, or even beer bottle caps.  An xacto knife could be a pole arm, a sewing needle could be a longsword, etc.

Enemies could range from rats to scorpions, while cats can be mini bosses. 

Perhaps mixing a bit of shadow of colossus as well, due to her small size she would need to climb ordinary objects like stairs, and I think a mechanic like that would play nicely with dark souls like gameplay. 

Here's some images showcasing her smolness.
