the use of simple shapes was a good choice, it makes the large amount of objects on the screen feel less overwhelming and more instantly readable. and the relaxing color palette is also really nice. I loved the crisp audio design when you deflect bullets and destroy enemies.
at one point, at the start of the game, I faced the hourglass enemy, he spawned on my side and I didn't understand how to deflect his bullets onto him, so I ended up chilling on the other side of the arena and gaining points. at some point I got bored and used a bomb to destroy him, but I think that if I did not do that I could keep farming points endlessly.
overall cool game, I enjoyed it.
