Chains is a game about linking 3+ bubbles of the same colour. It features 20 puzzles, each different from one another. Rules, objectives, layout change from one puzzle to the next, sometimes even the gravity is modified.
Basically though there are two types: puzzles that make you think a little, and puzzles where you have to act fast. Unfortunately there is much more of the "act fast" ones. When I got this game I thought it will be relaxing & laid-back. It wasn't most of the time. Chains require focus, reflex and speed, which makes it rather tense experience, stressful even. Hey, I'm old ^^>
I finished the game, although that turned out to be a test of patience. The progress I made was wiped a couple of times or rolled back (I had severe saving issues for some reason), so I was forced to repeat each puzzle at least a couple of times. Without all that repetition the game is very short.
I'm recommending this because "on fence" or "so-so" is not an option. Plus Chains isn't bad, so thumbs down would be unfair. Also, I like the music/ambiance, the art style/ design choice and the variety. I appreciate each puzzle being different (even though not my speed), as I'm often tired with games that have hundreds of carbon copy puzzles with barely any modifications. Ideas for some puzzles/ level design are neat as well :)
