TL;DR:
It's one of the most underrated and less-known games available. If you enjoy the grinding in RPG, a plot with various h-scenes and different ending, unique RPG system and a complete different UI than the usual games, this game is for you.
Pros:
1. That art style is unique, if you find it appealing, it is already worth your moment.
2. Multiple endings, worth replaying
3. Most of its system are pretty simple to understand.
4. The plot is fair
Cons:
1. It might get grindy
2. There are so many branches and options available, sometimes you just got lost
Honest Opinions:
Considering the fact that it was released so many years ago, you can only praise the developer for how much work they have done. Look at the UI, it is not your standard RPGM pre-made assets. The developer actually spent time to work on a separate asset for the UI.
Other than the details on UI, the amount of options available is quite fair. You can take various routes to get to the end. There are also various clothing to choose from (again, consider when it was released, the amount of clothing and the functions of each piece, they really made the game a pioneer of the flock).
Hopefully this simple yet detailed piece of RPGM game can leave you an enjoyable and pleasant impression (if the game didn't, the lovely and sweet smile from female MC should be able to melt your heart).
