loaded every type of shot into the gun at once and yuyuko died in two shots gg
Like the idea of this, though the shottypes could probably use some balancing - I felt like bouncing + spread (+ explosive) was pretty much all I needed to solve my problems; pierce was somewhat useful for going through boxes but the boxes are destroyed by regular shots pretty quickly already (and can be circumvented by bounce shots - maybe piercing would have more utility if it pierced through enemies as well?), and homing has enough of a curve on it that I had to stand at pretty precise positions to get it to hit enemies around corners.
Similarly the balancing on the bossfight was such that it either went one way or the other - on my first playthrough, I deleted Yuyuko's health so quickly that she didn't have a chance to start attacking, then on a second playthrough, I refrained from firing for a few seconds to see what her patterns looked like only to find that she spawned too many/densely packed rockets to dodge and was deleted before I could do any damage.
Sound effect/VFX on the regular/nonexplosive shots made them feel somewhat underpowered, though the explosive shot SFX/VFX and knockback on the enemies when they're defeated was good.
