Short and sweet bullet-hell game! Sound effects for bosses are very creepy... I love it! Especially with how they contrast pinball-like sounds of combat 🙃
The only problem I've encountered is the crosshair not being clearly visible - it can easily blend with the background, especially when there's a lot of bullets on a screen (like in the last level). I'm also not a fan of how the player transitions between levels - it feels too sudden. I imagine that was the easiest to implement 👀. Even something like a teleport token that drops when an enemy is defeated would do, because then you separate an action of defeating an enemy and moving on to the next level. But this one is really a nitpick.
Very cool entry!
