While at it, they might as well throw in more semi-continuous sexual implicating traps ( like rope-bondage, diabolic-bondage, wooden horse, full set of sex-slave attachment like a Slave collar + Heavy shackles + Heavy cuffs + Blindfold, lewd-crest, etc. etc.,


).
They could add in some sort of consumables (like a scrolls or something) to restore the Spell-counts of like, Mage rank 1~4 +3, Holy rank 5~7 +2, Mage rank 8~9 +1.
Also, add some more end-game clothes that will only appear starting from the last quarter of the game, you know, to re-spark our motivation after such arduous ordeal.
Now I have 2 more games waiting aside from this, 吾輩は鎧である RJ01228533 from ToraumaCompany, and CODE:VALKYRIE III RJ01282023 from Ulimworks (though they could use some darker tones for the character shadows, better jiggle physics, and sexier body motion for this, like Dorothy from Succubus Heaven)
