Neat implementation of the theme...
The game was simple, challenging and fun... Great job.
Loved the spider looking enemy that attracted the bullets... That level felt more like a puzzle than a bullet hell challenge, but not in a bad way.
the music felt nice too.
The only things that bothered me a little were the controls that sometimes the ship felt too fast and too slow at the same time to avoid some bullet patterns... Specially at the boss level. -> I played with mouse and keyboard.
And the one hit kill dynamic... But since the game has a fast replay, that's not really a big deal.
