This is a charming puzzler with great aesthetics. Every puzzle consists of moving tiles around while trying to complete different objectives. It's difficult at times to wrap your head around the puzzles presented, but that just goes to show you that although amiable and pleasant, this is a serious puzzle game.
Cogs is well polished and fun, but the puzzles were a bit too difficult for me. I got discouraged from continuing and decided to move on to other games in my collection. The similarity of all the tile puzzles can also begin to wear on you, but overall the level of polish brought with Cogs, the difficulty of the puzzles, and the charming aspects of its aesthetics (even the optional "cute" text) are enough to garner a recommendation from me. If you like puzzlers, especially involving difficult and mind-bending solutions, Cogs is worth your time and money.
