Labyrinthine Dreams is a short puzzle game with a story to tell.
What elevates this above a simple grid puzzler is the fact all the puzzles are actually a part of the story: it makes sense for them to be there, and they are not just thrown in to pass time between the short cutscenes. Cutscenes which are done in an anime style with fully voiced dialogue.
Roughly said there are four types of puzzles in this game, all with their unique move sets and rules. Each "level" is beautifully rendered, and has a score fitting the scene.
The game's soundtrack is simple yet beautiful, and the voiced parts are done by good voice actors.
All the dialog is subtitled as well and the voice can be skipped, not that I felt the need to do so even once.
The big minus point is that this is an RPGMaker game, and therefore suffers from the engine limitations.
The game has absolutely no resolution control: you either have to play fullscreen, or in a tiny window, and then use something like Windows' Magnifier to blow up the window.
The game can also be very short. Once you learn the trick behind the puzzles you can probably beat it in no time.
The big question then, is it worth €5? My answer is an absolute "yes". Even if you manage to beat it in an hour.
