I paid $1USD for this game, and even at that price I still cannot recommed buying it. There are three basic aspects to this game; a jigsaw puzzel, hidden objects, and a number of puzzle games.
Basically, you find hidden objects to unlock various puzzle games which unlock more areas for you to finish collecting the hidden objects you need to pass the level. The various puzzle games aren't bad, and in fact some of them are pretty good; however I still had a number of issues with the game play.
There are two types of hidden objects. Pieces to the jigsaw puzzle that you work on between levels and objects required to unlock the puzzle games or additional areas within a level. Finding the puzzle pieces can present a nice challenge, but the objects related to the mini games are beyond easy to find. The problem with this is that the puzzle peices are completely unnecessary. Whether you find one or all 25, you are given every piece from that level when working on the jigsaw puzzle between rounds. The game doesn't even keep track of how many pieces you have missed nor does missing pieces create gaps in the jigsaw puzzle, which would not only add to the challenge but also give the player some motivation to find all of the puzzle pieces. I also had issues with the jigsaw itself. Basically, every piece of the puzzle was identical in shape and all you had to do was assemble the pieces on top of a to-scale photo of the puzzle. Even the sky/background pieces offered no challenge what-so-ever.
I also found the lack of direction in this game to be a bit of a problem. The description states that there is no text, but there isn't even the tiniest bit of instruction when beginning a mini-game without clicking on the 'hint'. Playing through a second time, I've noticed that some of the hints are simply instructions for the game, while others are actual hints (Which I wanted to avoid using). This was a problem because at the beginning of each game, I found myself clicking around the puzzle a few times in order to see how the controls worked, and on at least two occasions my random clicking actually solved the puzzle before I even had a chance to actually begin. This lack of instruction also meant that the greatest challenge for some puzzles was actually figuring out what you needed to do as opposed to trying to solve the puzzle. Again, there were at least three or four puzzles that were both challenging and fullfilling.
The ending is beyond unfulfilling. After reaching the final screen, there is no "the end", "you won", "congradulations", nothing. You have an oppertunity to replay any of the mini puzzzles that you faced throughout the game, and after collecting enough bugs for a 'hint', the game indicated that I needed to play them. I only did so thinking that this was one final challenge before beating the game. I was wrong.
After beating the mini-puzzles a second time, I started a second game since I had missed a few of the puzzle pieces the first time around. I would have kept looking for them, but if you click on the last object of the level you are forced to move on even if you haven't found all of the puzzle pieces. I was hoping that finding all of the puzzle pieces would earn me some sort of ending. I was wrong. One play through lasts 90-120 minutes which actually makes this the most expensive game playtime/$ of any that I have ever bought on Steam; even after counting the second playthrough etc. I only got 4hours from the game, the rest was just runtime while I was away from the computer.
What really prevents me from recommending this game is the description. The store page talks about putting the tiny planet back together and helping the inhabitants etc., but there is no story in this game. Putting the planet back together involves the jigsaw puzzle which was unfulfilling at best, and helping the inhabitants means that there is a person somewhere on each level. Clicking on the person reveals their desire (that you solve a certain minigame) before they'll give you a key or one of the hidden objects you seek, but never once did I feel like I was helping them or even that they had any sort of personality whatsoever.
Ultimately this game was unfinished. What starts out as a cute puzzle game quickly turns boring and repetitive in less than an hour. Also, considering the amount of content, this game is grossly overpriced even at $1USD.
