While I certainly won't say I necessarily agree with the price of this game (especially since I got it from a humble bundle pretty cheap), I will say that this is a very nice, relaxing game that's definitely worth a playthrough.
It's a very simple game, so don't expect any super in-depth challenging gameplay out of this, however there are a few moments that will require you to think a little more critically. Generally, the game remains pretty easy and just as relaxing all the way through. Definitely a good thing to do if you need to clear your mind and if you're stressed out.
The forefront visuals are very basic and unfortunately there isn't much support for high resolutions at all, so fullscreen will have you super zoomed in sadly, but for what it's worth, the backgrounds are very nice looking and are probably the strongest point of the visuals. The sound is also really nice. Not very much sound as far as what you do, but the very, very calming soundtrack that's more or less just ambience really helps add to the relaxing mood of the game.
All and all, I'll say I recommend it. Even though it's another indie puzzle game, this one has always stood out for me as one of the best designed.
