Awesome idea! It doesn't get any more chaotic than 100% RNG.
Even though it's meant to be random I wish the player was given more time to get started after dying. There were times where I'd respawn on a bullet and die immediately, or be immediately swamped by a hoard of enemies. Maybe have the player start somewhere away from the enemies, or have a max number of enemies that can be spawned within a certain radius?
Overall I thought this was a neat, experimental little game. Nice job!
