This was a really cool concept! You executed everything on the gameplay side completely perfectly! I liked that the block can interact with the player character while you're controlling it, and I actually figured out how to move myself before the levels told me to.
AND GOOD JOB ON THE TUTORIAL LEVELS! Games are so much more fun when each concept is explained one by one. Nothing worse than a giant HOW TO page. I loved the messages.
Of course, the graphics aren't the best, but they served their purpose and it doesn't matter, the gameplay was excellent. I liked this one a lot.
Good job!
