This is a cute and quirky twist on a bullet hell game. I like the 3D art and voice acting and how there's a shop in the middle of the stage that's accessible at all times. I don't like that the health indicator is so hard to see, the "E" meter appears to be meaningless, and that I take hits even when the shots are nowhere near the character.
I also like how the waves are more organic and the enemies take more hits as the game goes on, encouraging me to flesh out my arsenal and upgrade it.
Being able to go outside the bounds of the screen is kind of weird. It's OK since it means that I can avoid damage or getting trapped (especially since the battlefield is pretty small), but it feels like I'm cheating. Also, the character moves very fast - it helps me avoid enemies & damage, but it also feels like I'm going way too fast. I would also like to see the enemies change form as they get more challenging so I understand that they are getting harder to kill, rather than being a bigger bullet sponge in the same costume.
It's a fun game, but it lacks polish. A fine start to continue developing on should you choose to, but it's otherwise just OK.
