After playing around 20 levels, I think I can say with certainty that this game is more about luck than skill. For the most part I found myself trying the same thing over and over until it worked.
Well I normally don't like to flame but... @jront1 - you played through 200 levels of a game you didn't like? Even if you took 5 minutes for each level, that would still be more than 16 hours of gameplay. Sorry, I don't believe you.
Oh yeah, the Custom Game achievements... I had forgotten about those. There's something else I was planning to tell mrsneeze - add some constaints to the possible choices in Custom Game, otherwise a player can go for ridiculous combinations.
Oh and now that I mentioned lightshift: I liked that I could see which square I was clicking, could you add an option to make the grid visible in this one as well?
Also, to those folks complaining that the game is a loops of zen clone: PLAY LIGHTSHIFT FIRST! I just did, and it's perfectly clear that colourshift has everything in common with lightshift. Except for the graphics, no other ideas needed to be "stolen" from loops of zen; they were already there in the prequel (lightshift). The only gameplay element that wasn't there was the different colours, which is an ORIGINAL idea.
When you're working on a large grid and you have only one or two unlit lights left, it's hard to see where they are. You should make them stand out somehow.
I actually liked this one almost as much as the other Perfect Balance games. Yes, most levels are too easy, but there are some not-so-easy ones in there as well, and the "playground" quality is fun, in that you can try stuff and see how it works out.
Silly premise (getting things lined up), annoying controls (hard to adjust speed), but still fun. The graphics are very nice, and there's a lot of humour... overall, 3 stars.
