very satisfying 3-phase boss fight! i was very pleased that the drones had super-clear tells, PLUS their attacks were still satisfying dangerous and scary :)
i knew the drones were invincible because i read the itch-page description, but otherwise it might be nice to maybe give them a more muted color to make them feel less damage-able, or give them a "clink" sound effect when you hit them so it doesn't sound like you did anything. that and maybe changing the boss's color to be higher contrast, like maybe a gold or white or something!
that was a long sentence to say - i really enjoyed the game, and there was some info that i had to get exclusively from the itch page, and once that is conveyed in-game as well it'll be even better!
