Logic

Would be good to have an android version of this.

Hmm! Making the levels bigger doesn't necessarily make them more interesting. When making a puzzle game, I find it helpful to think not about how "hard" or "easy" the puzzles are (in terms of the mental effort, number of moves, or whatever), but instead to concentrate on what part of the puzzle makes us want to solve it.

Some of the larger levels had a variety of solutions, and because we are given a score based on our choice of paths I found that interesting. You might try also visualizing the puzzle as a train-track. One or more branches should lead to the goal, and the rest should lead the player in loops.

That's what I think! I got to level 13 with about 100% (one level I got 86% and one I got 112%).

That was fun, didn't pull me enough to keep going at it though, a bit odd. I usually get a bit addicted in these type of games. But good job overall, and yeah a bit colours would go a long way. xP

It's a good game at quite addictive, but I agree, maybe more variations in the colours

Good game, if not anything special. I would have liked variations in color palette and maybe sounds, but they're just candy.
