Very nice game! I'm a big fan of big numbers that keep on increasing, it makes me feel like I'm actually achieving something :D
The width of the sliders was pretty mean because they changed mid slide to fit the large numbers, a fixed width or aligning the text to the left might help with that.
I burned at day 54 because I accidentally got too much defence, and all of the large numbers kinda blurred into a giant pile of digits XD
The atmosphere and aesthetic were wonderful, the UI and their animations felt quite polished, and the sounds of plague will never not be funny.
Neat job!
