Nice and short SHmUP game. I see it's pretty accessible.
I really like Sakuya and Tojiko's teamwork in here. Concept cool and well executed. You just need to make the magnet gauge easier to look at because it's attached to the boss, whereas the player's eyes will be on the player character (the lower half of the screen) most of the time. (yeah, having to look away from your character isn't practical).
I wonder if it's a bit too easy, I didn't even have to use Bullet Time. But I'm a regular shooter who am I to say that lol
