Yeah. it's really late but I figured I'd fix it haha.
Deaths will count even if you return to menu now.

"Fixed" an issue with the "smushed" screen but now it may cause issues with those with lower resolution. (Will try to fix)

KNOWN BUGS:
- Deaths don't count across multiple play sessions

- Spawning issues during wave start ups

- Infinite mode timer issues

-Steam Screenshots don't work currently
Also amazing art made by Jchoco!
