I know that the developer of this game is probably long gone, but the idea for this game was pretty interesting and the story wasn't bad either. But I do wish there was more interesting content in the game, maybe like sub events or side quests where a some older women have like mommydom vibes where they take the MC into their care and keep them as their own personal playthings. Like have one female character locking you up in your baby room and you try to get out, but if you do, she then gives you like gloves or mittens where you are forced to crawl like an infant, because she made your hands and feet rendered useless, which makes opnening doors or interacting with objects/items worthless, except for playing with blocks, stuffed animals or whatever. Another female character could be interesting is a mommy hypnotist, where she lures you in with different hypnotic techiques like a lullaby, a pendulum or pocket watch, TV that has a special channel that brainwashes girls or boys into thinking like infants and calling their new mistress mommy, a hypnotic rattle or pacifier, breast milk, etc.
I only seen like one female side character that has those vibes in one of the houses, but she only does spankings, which is pretty much the same repeated animation over and over again.
I do like the supernatural/ghost theme in the game as well. It kind of reminds of the game Psychonots in a strange way. I also would have liked to see more of that supernatural/weird element that is just more then fighting. Like since the theme is ABDL, you could have had some female ghost enemies that also give off mommy type of vibes and if you loose to them, instead of just a simple game over, they take you to their realm and never releasing you back to the human world and keeping you as their child forever, you can have sub events in that world as well after being captured by the ghost mommies. Just a few ideas I personally came up with that could have made the game more interesting. But that's just my own personal opinion.
