I won! Boss battle time was something like 106 seconds I think, it took me a few tries to beat it.
The game is engaging. I like the hypnotic visuals, music and pacing, it's very immersive. There are some variations, the length of the game feels right and the boss fight is specially fun. Difficulty is overall fine, some earlier parts might probably have been a tiny bit harder but the boss fight was perfect.
That's a cool game, thanks for sharing.
