I absolutely loved the idea you were going for, however, one thing really sucked the fun out of this game for me. The game DESPERATELY needs a limit to the amount of spam that can be spawned at once. This causes several issues which I will list below:
1- Turn the game into a idle game: When I first started playing, I really liked that you had to zone out the spam to prevent them from reaching safety. But, since the entire screen quickly becomes covered by spam on day 2 (with no spawn rate upgrades btw), any form of strategy becomes unnecessary since you can just randomly walk around and catch spam because there is so many of them. 
2- Make the spawn rate and mega spam upgrades completely useless: As mentioned above, the entire map is filled with spam even without any upgrades, so there is 0 reason to make the spam spawn faster. If a spawn limit was implemented, you could make the spawn rate upgrade also increase this limit so you could still get the low fps chaos which I assume was intended from the <5 fps ending. The abundance of regular spam also make the mega spams irrelevant since it's just faster to run around and collect spam instead of wasting time killing mega spams.
3- Make the sfx really annoying: When there are spam everywhere, all you can hear is the gasp sound and the nom nom nom sound getting cutoff and starting over constantly which gets deafening after some point. This is a real shame because I think the sounds are actually lovely when they are not being spammed 24/7.

That being said, still, I enjoyed the core of the game. Props to you for managing a game jam alongside a full time job!
