I enjoyed this a lot!
It was a pretty well implemented game, though I would appreciate it if the game's difficulty increased with survival time because once the breakaway happened it ended up feeling a bit aimless because the failure state to purchase more items felt so voluntary.
I did end up playing long enough to obtain every item and getting the free state of mind because the feedback loop of checking out better and better items was satisfying.
The sound design and graphics were fun to look at and listen to.
It seemed a little glitchy if you let the negative thoughts cross through the center, causing spikes to appear and the fill to despawn as the model inverted on itself, the collision detection there also could unexpectedly pierce you.
The concept of your own bullets forming the bullet hell was really interesting. I had some issues with visibility on certain bullets, and it felt particularly assbackwards that the bullets that don't hurt you on rebound are specifically the ones with the spikes on them.
Some of the quotes hit pretty close to home, haha.
