I considered having a stats page/GUI to display your current unlocked weapons and power, but never got around to it - having some sort of visual notifier of what your cooldowns are would 100% be a good idea. Will keep it in mind for potential further upgrades down the road!
4003, well done! Admittedly i think i overtuned the difficulty a little lol - i reached 16000 in earlier testing before dramatic balance changes, and now reach more along the lines of 1500-2000. How was the performance at the end of the game? It seems to struggle or run smoother depending on the run - maybe thanks to swifter enemy kills with different weapon combos. And whats your favourite of the four weapons?
