This was a good time. I liked how there was a real entire arc of gameplay here with the objectives and extraction. I escaped in 7:21 with a score of 9254. The world environement size was perfect for this kind of game and I enjoyed how the enemies dropping down kept the pressure on. The way the music amped up during the intense parts was a nice touch. The enemies behavior could probably use some tweaking-- they follow the player position and clump up so it was fairly easy to just continuously circle them with the only really push/pull being do you want to take the risk to dash in there and pickup the upgrades. I'd also add some kind of impact particle effect or other feedback (audio?) for the bullets. The hitbox for the flying guys felt a little off to me.
Overall I enjoyed playing this one a lot, great job!
