I love the puzzles! managed to get to level 8, and gave up on 9. I know the correct placement but just can't seem to find the right move to solve it. Anyway great work on this game!
Thanks for playing, and I appreciate the kind words. I had plans for a "Blueprint" hint system, where it would be a rough sketch of what order and where certain boxes should be pushed, but I didn't find the time to implement it.
