Wow, the artstyle is PHENOMENAL! where did you learn that from? The character, the enemies, the boss, and the shop... just perfect. The music and sound effects were also amazing. The gameplay itself is also great! The difficulty ramp is well done, and the shop system score system was also pretty forgiving.
There isn't much to add, except for maybe some qol improvements, like adding sound or screen shake when taking damage, and making the boss' bullets not shrink so that it's easy to see, and maybe making evershot something to start with, because having to click all the time to shoot did get a little tedious.
Other than that tho, this was very impressive, especially for being made in only 3 days. Loved it!
