The gameplay seems to be fine, but I can't help being bothered by the awful amount of grammatical mistakes. Please, try and make sure you have a few proofreaders before releasing something! Otherwise, though, keep up the good work. :)
I barely ever come back to a previously played game, let alone as much as this one. I absolutely love the game and its possibilities, from the fine-tuning the flow of a line, to finding completely alternate solutions to them; I've had a blast. The low entry barrier is a great thing as well, it allows for new players to enjoy the game while learning, while people more experienced with this type of concept aren't limited with what they can do. Excellent!
