Awesome little game! I really like the gradual introduction to the main mechanic. It allowed me to figure out the puzzles and solutions without looking at the description to figure out what I needed to do.
One small problem I encountered jumping toward a block and then facing the other direction will not pick up the block which allowed me to complete a few levels in a unintended way. But once I figured out that it was not a mechanic I was able to finish the rest of the game.
Overall really fun!
