Nicely done! Just like last year I'm a big fan of how you've made the game feel like a relatively complete experience with a lot of content considering the jam time.
I played through all levels with different loadouts. I think that the main thing that would improve the experience for me would be better weapon balancing and making it generally harder, but I'm guessing that this has to do with the limited time available.
The varied win conditions are a nice touch and my favorite part of it has got to be the chunky pixel aesthetic! Fun game!
