Takes a bit to get the hang of it but it's really cool! The concept of your own tail being your ammo reserve and needing to eat it to reload is badass, and it adds an interesting element where the more resources you have the harder it is to dodge attacks.
The fight was a good challenge, I like the snake inspired hazards that spawn in later in the fight, and it was satisfying to beat it after a couple tries. It was a bit annoying though when you run out of ammo and extra tail, so you either have to wait for the boss to drop some purple or die on purpose.
Vibes are great, love the abandoned facility aesthetic, and the humor was a nice touch. Overall I had a good time playing it :)
