Nice little game!
I like several parts of it
1. The art is consistent and looks nice, adds up to the atmosphere
2. The time pressure adds fun
3. Death animation is very well done
One improvement for the future. I did not get the refilling too much, it feels like you are planning to have it at some later stage I guess? Some refill stations
(I just noticed that it's a submission to the game jam. I am not coming from the jam, just was casually browsing the new games :) )
