It is a really fun game and i think you will work on it more but sometimes the mechanics don't work the way they should (if you put 2 blue pieces so that the one is pushing the other, the first will sometimes go 2 spaces and sometimes 1) and if you change 2 of the same pieces in eachother's position the result usualy is completely different than not changing them. Which could make it really hard to complete a level (even if you were doing it the right way all along)
