The only quality that saves this game from a 1 star is the beautiful art. Otherwise this is simply a short(?), unfinished, unpolished scene collector with very little to actually do. There is a pervasive sensation throughout the game that you have somehow broken a quest trigger (or several), dialogue is sometimes out of order, sometimes you seem to get some kind of progression only for nothing to happen. The text crawl is agonizingly slow and cannot be changed. I swear, even so much as clicking on an npc takes 2-3 seconds, which is especially infuriating since the gameplay loop seems to be as follows:
1. Make money through prostitution (a bunch of text) or gem mining (slightly less text but lower returns).
2. Buy a gift (the merchant has text).
3. Give gift to girl (more text) and hope she likes it.
a. If she does, repeat 4-6 times (with identical text every time) until she reaches an affection threshold, which might (MIGHT) give you a scene.
b. If she doesn't, you lose affection, and have to repeat the loop even more times.
4. Have Lilyna's quest trigger break so you spend 25-ish day cycles for nothing to happen.
It is dreadful, not made any better by the map being claustrophobically tiny, yet somehow still feeling empty, and being just large enough for the slow state you are put in after underground prostitution to get extremely aggravating, which you also need to cross the entire map to get rid of. Overall, terrible game, don't play it. However, it might be worth downloading for the scene rip alone (or better yet, just downloading the images someone else has uploaded). There are some very nice pieces of Kazuko and Tsumugi getting dicked in there.
