So, I was able to finish things, but overall, I think that this would benefit from

1. A faster walk speed, or a smaller level
2. Ammo bars on the enemies
3. Something to vary the pacing. Such as enemies with belt-fed machine guns, where they run out and take a long time to reload, and if you can get one, then you can use it to destroy crates or something.
4. Negative space in the level. Right now, there’s a lot of level, and almost all of it has enemies.

It did keep me engaged from beginning to end, though, which means it didn’t stop me from finishing it. For a game jam entry, that is a feat.

(A note on difficulty, I mostly didn’t need to backtrack for medpacks, and ended up skipping quite a few.)
