I liked it! It has a fun gameplay loop, it actually made me play it for a good bit.
Would maybe try to make the beginning text a bit shorter to get more quickly into the action. I could tell from the text that you put a lot of care into the character and into the world she's in, but having all of that info condensed with the tutorial text made it a bit harder to digest, and still made me feel a bit lost after reading it. If you slice it into small-sized sentences or maybe distribute it into voice lines from Lucy, and scatter it across each element of the game, I'd say you'll have this issue sorted, and will also be able to get across some of the story and personality from your character.
Other stuff is some smaller bugs or wonky collisions, but in these jams sometimes those are hard to figure out in time. One of these issues was the zombie waves not having a counter and not scaling enough to make it feel more challenging(this was the main reason I stopped playing after a while).
I will say though, the electricity minigame was quite fun, once someone get's the hang of it I was starting to try to make it the faster I could, maybe adding a bonus to minigame completion time in some manner would be interesting. Electricity shutdowns could use a cooldown tho, I was mostly just going up and down the basement XD
Good game overall, might try the prequel, cheers!
PS: Was there supposed to be something in the down-left corner room of the map? o.o
