Absolutely stellar concept, and really well polished.
This is going to sound really nitpicky, but this is a fantastic entry so you get my most minor criticisms ;) the font and colours are a little too difficult to read, particularly on pause/game over. I also think the penalty for hitting something is a little too mean, but that is definitely because I'm terrible at the game 😂 maybe make the hitbox for the player more generous? A lot of shmups/bullet hell games give you a teeny tiny hit area.
But honestly I'm only finding small things to complain about because it is such a good entry. The art is fantastic, the concept is unique and interesting and it is executed really well. Great job!
