I really like the minimalist black and white presentation. The animations are beautiful and fit the art style perfectly. The sound design is excellent as well. Despite the simple geometry and limited palette, the game feels full of small details, which I really appreciate.
My highest score in a single run is 132,800. I ended up stacking multiple diagonal weapons with a very high fire rate, and eventually the entire screen was filled with projectiles. It felt incredibly satisfying.
At that point though, with so many bullets on screen and the movement speed being so high, I sometimes lost track of my ship and ended up colliding with a boss and dying. If that is an intentional risk-reward part of the balance, it makes sense. Otherwise, maybe the player ship could use a subtle visual distinction, such as a slight accent color like red, or even a selectable color upgrade. That might help with readability during late game chaos.
Overall, really impressive shooter. I had a great time with it!
