I finally managed to beat that boss level everyone says is impossible... but honestly, I think I just got lucky with the hitboxes. The timing window is exactly 0.03 seconds, which is tighter than most rhythm games. Usami was cheering really loudly, though! She says my focus looked 'magical,' but I think I just forgot to breathe for a few minutes again. It feels good when things finally click into place, even if your fingers are shaking afterwards. I'm going to celebrate with some strawberry juice and a nap. Maybe... I think.
