Hey all, stand by for a set of 25 or so pre-generated "Puzzle" levels which should hopefully remove the monotony and also help you learn how the various colours combine. I should be able to get this out in a few days!
Thanks for all the comments.
My idea was that the rules over time slowly explain themselves. Looks like its not as intuitive as I hoped.
In terms of a sense of achievement ... anyone have any ideas?
Level Editor ... sounds like a great idea. I've putting them in my mobile games lately, I think I can squeeze one in to this :)
