The theme of the game itself is worth the 5 stars, a little elf sister, there's no way it can go wrong, I just don't give it 5 stars yet because the game is very dry and very much in its early stages for now.
But that doesn't mean the game doesn't have its flaws, especially since the game is in such an early stage.
I won't go depth in the topics, I'm sure most people have already tested the game, version 0.21 is unplayable and very buggy, version 0.22 is already playable and fun, but missing several things, missing several interactions with the little sister, but as I said above, the game is very early, so it's ok so far.
Like most RPGMs, combat is kind of useless, that would be my biggest complaint with the game, the story gives that cliché excuse that the little sister is weak and needs something that can only be found in dungeons, there's the excuse to wake up every day at 7am and go out killing random creatures that so far aren't worth it except to collect money, nothing else, like I said, there's still no reason to fight there.
I would particularly prefer the game to focus more on everyday life with the sister and the story with her than on the fights, unless she can help us in the dungeons even if it's just as support.
You can return home early, even though you've already left home. However, since you don't have much interaction with your sister, you soon run out of options and all that's left is to sleep, but it would still be 1 PM or even earlier than that, and the game bugs out if you choose to sleep early like that.
One thing that leaves me in doubt is that so far there are no sex scenes and Asian games are usually boring about that kind of thing, the Asian version of the game no longer has BJ in the files so far, so I wonder if in the future the game will just be something light and superficial with the sister or if we will actually have sex with her, only time will tell.
The food and cooking part needs improvement, no matter what you choose to cook, even if you choose the same ingredients, something different will always come out every time, or most of the time the food will come out spoiled and bad.
I would say the game's greatest quality so far is the art and the few interactions with the little sister.
