I have no idea how this has anything higher than a 4 star. If I imagine someone who has a goblin kink, I imagine that person would give this a 4 star. Best possible rating. It's not amazing, it's not terrible, it is very average. The artwork is fine but not great. The animated scenes are few (1? 2?) and have like 3 frames max on loop. The story is okay but not very deep or long. The combat is okay but not very exciting. So on, so forth. Literally everything is just "okay".
When I play hentai games, I'm usually of hentai first game second mentality. I appreciate some build up and fun mechanics (ideally ones that lend themselves to the hentai aspect such as the "papers please"-themed Imperial Gatekeeper), I can play for hours without any sexual content and be content if the payoff is big, but this is just.. acceptable. Wish I had not wasted my time on it, thanks to the other 5 star reviews (5 stars means excellent btw, 3=average)
To above review trying to explain star value meanings, no, 5 stars does not mean good, 4 stars does not mean good with reservations. When you mouse over 5 stars on this site, it literally says "Excellent". 3 stars literally says "average". Stop trying to reinvent the wheel.
