Bicolor 4+

Bicolor feels like many other draggable-ribbon type puzzle games (folding paper strips or filling or emptying space) -- but more refined. Controls are simple and feel good, with a relaxing rewind-mistakes style of gameplay that makes it as easy to fiddle with different solutions as it is to start over, and the many possibilities make play feel creative. There are so many included puzzles that it is possible to start one over and have it feel fresh--especially given that many puzzles have multiple solutions. Nice color scheme.

It could be improved by adding a solution-replay option that allows the player to enjoy re-watching how they just solved a puzzle -- or to share a solution.

This game is as beautiful as the screenshots and video show it to be. Movements feel super natural and it is oh-so-satisfying to finish a level. What I love most is that whenever I'm stuck on a level, I leave it for a short while and when I come back, it's with a fresh mind and I am able to easily solve it. Puzzles never feel impossible or so frustrating that it takes away from the enjoyment of the game. I also like how undos are unlimited, so you can go back to whatever position you might've messed up on and work from there. The color schemes are overall okay, but the gameplay is very entertaining. 1Button, I applaud you.

I, being a lover of simple iPhone puzzle games to play while I'm waiting at an appointment, sitting in the car, or other times where I'm out somewhere in need of something to fill a few minutes, decided to buy this game with a bit of change i had left in my virtual wallet. What I didn't know then was this game was going to have such a grip on my attention that I would be at my desktop computer dying in online shooters because I can't stop working on these puzzles. Buyer beware: dangerously addictive, will keep you up at night.
