No need for a goal
Although the transition between the levels could be indicated a bit better just to make it a bit more interesting. Some stuff like joker-blocks (fits anything) and non-pickable obstacles can also add to the (heaps of) fun (and frustration) while playing this little piece of flash-mastery.
This was actually very enterntaining. The concept is very good. Makes you think :P and fast. Very good game!
This was done extremely well; so well that it's almost addicting. But it's also challenging, especially with a track pad. Keep up the good work
This works real well -- I don't have any real suggestions. Anything you added at this point would be just window dressing - it works as is and would likely just gild the lilly.
simple gameplay, but it hooked me. It took me a few tries to really understand the mechanic (the first time through I thought I was stuck being "red" unless I wanted to take the plunge and lose the chain for another color ;) ).
High score--GUD Magazine. For now, I'm sure. ;)
