One of the best games around, "Long Live the Princess" brings you an engrossing story in which you must improve yourself. Not just for points though, you're constantly learning in there, and absolutely every detail matters, as information is all around for you to solve several things happening, from finding a criminal to getting into someone's panties.
The navigation system is just fine, taking almost no time to get into somewhere. There are a lot of events happening, which makes you never skip a part of the day. Some hints to find them would make it even better.
The characters are very well-built: each one has a very singular behavior, making the conversations feel very organic, especially with the pixie and all its humorous conversation. Other ones are more of a hard shell, like Primrose, a very closed girl who's not used to many social interactions, and the main character himself, who needs to build up his confidence during the story.
In terms of image quality, no complaints. The poses are also very organic, and there's no exaggeration in color vibrance, characters physic attributes, etc., which is a huge plus in my opinion.
This game may not please some players due to its huge amount of content and relatively slow build-up, plus the non-stop attention required to gather all possible clues, but, still, it all worth it.
For me it's a 5/5.
