Fun game, I loved the art style especially.
Wish there was more of it! It was hard to test out different bullets because it was rare to get enough shops + enough money to keep buying them in one run. I played a few times though because I did enjoy myself. The ending was a little anticlimactic - after beating the boss it felt very sudden to just get dropped back at the title, I would've liked a bit more fanfare and celebration for my monumentous achievement!
Needed a little more spinning, but other than that, great entry.
