Great variation in upgrade paths and a very comfortable climb from crawling through the abyss to feeling genuinely, insanely strong and holding off the hordes of enemies. Really well executed and has a good lifespan given the different enemy types - far, far beyond the scope I was expecting when I came into the game. I'm not sure there's much to add that the other jammers haven't already touched on - just a fun game and nice achievement for a few days of coding. Great work!
