I finished this game as a steam version. I originally bought this game accidentally as a part of humble bundle including both DRM free and steam versions. If you love puzzle games like me, this game is a must to have. The main concept of this game is to construct certain chemicals by connecting various atoms which are located here and there inside the limited space. One of the atoms can be moved by the gamer. When the atom gets close to other atoms, it makes a bond. You need to do this until you connect all the atoms and make a targeted chemical. For instance, you have two Hs (hydrogen) and one O (oxygen) inside the limited space. You move one of H atom and connect to O atom. Then you move H-O (a chemical under construction) and connect to H atom so that you can make H2O (water). For assisting construction of targeted chemicals, there is a tool which enables you to rotate your chemicals under construction. There is also a tool which cuts bonds. Sometimes you need to make double and triple bonds for making targeted chemicals. It is easy when the targeted chemicals are simple. But once targeted chemicals become complex, it gets very difficult quickly. An important factor to consider to make chemicals is a limited space where you can move around your chemicals under construction. When the size of chemicals under construction becomes pretty large, you don't have a lot of freedom to move it because of limited spaces. This makes this puzzle game very difficult. You don't need any knowledge about chemistry although all the targeted chemicals do exist in reality. If you are a puzzle game fan, you won't regret to get it. Even though I finished this game already, I might get a GOG version when it is in a huge sale (such as 75% discount).
A very good puzzle game. The nature of puzzles are varied so that you don't get bored easily. Sometimes you need to use your creativity to solve puzzles. At some stages, killer robots will appear. To deal with these killer robots, you probably need to move around your robot a bit quickly. Other than that, the pace of the game is very relaxing. According to some review sites, there should be 25 stages. I so far finished 8 stages. It took me about four hours to reach this stage. Then the length of the game should not be that short. Graphics is pretty nice. If you are a puzzle game fan you won't be regretted to buy this game.
