This game is a lot of fun. It's true to the source material but lewd enough to be fun and hot. If you don't mind a few suggestions, I have some to share.
1: The mask item. Perhaps after you pick it up, you start to insanity before getting forced to wear the mask and fall victim to it. The girl wearing the mask becomes an enemy who either fucks the next girl or drags her to a monster
2: Chest menu to play the game without worry. Something similar to the ghost hunter (you can find the game on gamcore).
3: Maybe more maps like the desert or the mansion.
