I was looking at most of the comments and then I took a stab at level 6 as I already did it a few times before. After countless more tries in going to complete it for the second time, I started to think, "The Tip says to be quick, but how the hell do you be quick with 1: Wall blockers and 2: The map closes in on you after 5 seconds.
1/5 - This game has a lot of levels and for that you need to make it appealing for the new puzzle users, or else they'll stop playing after the first few tries.
Was looking at the all-time score, and saw a guy with 100mil. Is that even possible? Everyone else is stuck in the 100thou. Good game, 4/5. Would be nice to compete :)
