Fun stuff! 5 and 6 are really nice. Number 3 feels a bit inelegant since you can solve with a red or a yellow on the goal, but not a big deal. Thanks for sharing!
aaargh... i hate anti-cheesing lvl 3
i'm probably going to scrap the whole level. the point of the level was to create a line of 5 with the reds and clear all of them at once btw.
