Bicolor is a fun little puzzle game with very little issues. Then again, the gameplay is also pretty straightforward, you have to fill the screen with one color by moving tiles around. They have a number on them, and that’s the number of squares you have to move them before they disapear.
The challenge comes from the fact that later levels have weird layouts and if you don’t think hard enough you might get yourself stuck in a unwinnable position. The game has good tools to help the player with the trial-and-error aspect it sometimes has, you can undo and redo and move you make and restart at any time (not a big issue but I wish the button to restart was always on-screen). The earlier levels are very easy and it gets progressively harder - as it should.
It’s a bit tough to plan your moves in Bicolor, so you’ll fall into trial-and-error quite quickly on the toughest levels. Succeeding by pure luck isn’t that fun, but again with big maps and tons of tiles to move around, it’s quite impossible to visualize how the perfect solution will go on your first try. But it controls fairly well and nothing about it is too frustrating, almost, so you won’t get too bothered by having to do some stages multiple times.
That being said, there is no way except by paying money to skip a level if you’re stuck on it. There should be, I think. Or at least a hint system to get you started on some of these tough levels. The game was already non-free, I’m surprised they went that route.
And the game is fairly agressive with full screen pop-ups and requests for you to rate the game. If you say you don’t enjoy it, they ask you to send an email and will keep asking you non-stop. That’s a bit of a turnoff in a way, it made me like the game less. It’s a fine puzzle game, but it’s a bit simple and some of the stuff around the game is annoying. I liked it enough to complete all puzzles, but that went pretty fast by.
