Its content justifies
a roughly 30-minute game, but is padded gruelingly to become a
2-hour game. If you like NTR and writing, this game is annoying because it falls under every bad stereotype about NTR stories. It's absolutely carried by the polish of the art and overall presentation, I haven't seen much better human x goblin art in a game before. A game that had high potential and was spoiled by baffling design decisions.
The Queen and her son are the two POVs, but you
can't play the Queen at first, it locks you out until you play the son's POV. You are given a lot of fake choices, but the game really just wants you to play it multiple times to milk the content. When you play as the Son, you get voyeurism where you only see glimpses of the scene. As the Queen, you get the same scenes plus a couple in full.
Make sure you get the patch, so you don't miss out on one of the ending scenes. The multiple ending idea felt like something thrown in at the last second, as it's really not fleshed out. The best comparison I can make is Mario Galaxy, when you beat that game the game says "alright, now beat the whole game again with Luigi." which is kinda fun but also tedious.
I love goblin stuff, NTR stuff, voyeurism, and so on. Really, I'm the exact target audience for this game, and that said, getting to the content is kinda grueling. You would have a better experience just looking up the art and imaging the scene yourself. One thing I appreciate is that this game isn't censored, as monster fetish seems to be bigger in Japan.
It just for me didn't work well as a game and I got pretty sick of it. There's nothing wrong with making a short game, but I didn't like how this was done here because of the multiple POV and the "multiple endings" felt like extreme levels of padding. I would have actually preferred that they ditch those concepts and make this a 20-minute micro-game instead. The game itself in programming is very stable and from my experience without bugs, it's hard to mess up a VN game, but even still the programming here goes slightly above and beyond to make a very polished VN engine.
The "animation" is just fading between 2 frames back and forth, but it's serviceable. It's worth mentioning because I've seen good fully animated scenes from this same ntrman in other works
