Whew! I just finished all 40 levels. This game is really addictive but the easy thing is that you have no move limit, like mark0 said. But, alone, it's already challenging enough.

EDIT: ssjtrunks, in case you still need help, this is how I completed level 8:

Move the 2 top horizontal blocks all the way left. Then, move the 2 middle vertical blocks all the way up to the top. Move the vertical block to the right of the middle block up, so that way you have something like this |||
Then, move the blue block all the way to the right.
Move the vertical block at the bottom up to the top, right below the first vertical block. Like this: |||
|
Then move the 2 pale horizontal blocks all the way left, move the small dark horizontal block left, then move the pale vertical block all the way down. Then move the blue block to the exit.
