I get the scene where mc "loves" right on Sacura's stomach about several time, around 5-7 times and get the glitch with soft lock on the screen, when opening last save it gives the same scene with the same glitch. I don't know how to describe it any way else
Also Mitarashi was quite easy: stun them all; kill a and b tentacles by mass spell and then thrown on buffs while keeping in stun the Mitarashi's own; long process of killing Mitarashi's own; then beating Mitarashi by heat and charmed debuff... And whole time keeping praying that charm won't drop off giving Mitarashi mass attack that instakills.
You need to nerf stun and charm mechanics if you want the game to get harder. Giving stun defense for x turns and charm being separate from main turn act for example.
