Love this game! I have saved it to come back to so that I can try and get a perfect run! I love the different velocities of attacks/bullets, it creates a bullet hell minefield with only a single enemy, really cool! I don't know if this part was intended or not, but when you die, you come back to the same enemy but with full health this time. Honestly, I think (intentionally or not) the subtle strength boost to the player after dying is pretty cool, although with the potential side effect of devaluing the urge to stay alive at all costs. But again super fun game!
