Although i personally love this game, i know most people won't. Why? Basically this game is the closest thing as an "abstract art game". Story is interesting and suspicious. Levels are creepy and interesting, even being small ones. Gameplay mechanic is unique, you have to use different colors to use attacks. You have to harvest this colors from the gardens so you can keep them in your body, they are also your "HP" as well as your attacks, so you have to manage both. You also can give the colors to other npcs so they can live again. This game is hard, i tell you that, it does not tell you what's your objective (not directly, so you will be confused if what you are doing is correct or not) and the game does not hold your hand. Boss fights are tough as hell if you don't have loads of colors with you. Also you have a big feeling of loneliness and tension while playing, even tho this is not a horror game. Some characters looks like monsters coming out of Hellraiser.
Also be aware that you walk around a lot, and combat is not real time. When choosing a color the game enters in slow motion and you can choose how much color to use to attack someone or give someone. To make some actions and magics you have to draw different shapes (they show you the shape so you can copy in the bottom of the screen), which i found really interesting. Again, this game is really hard, so it won't be a walk in the park and you might get bored of going around, coming back to get color, etc. Another tip is to save whenever you can, because if you run out of color (meaning you will have 0 color with you) you die and can only go back using a save file.
Conclusion is: I won't recommend this game because it is a bad game, it's not, but i am sure most people will hate it, so it's best to save your money. If you are interested in a surreal game, with crazy worlds, crazy npcs and crazy mechanics, you might love this as i did.
