Very well done! At first I was a disappointed I couldn't pick up blocks below me, but once there's a floor of numbers the game kind of turns into a type of alchemy solitaire warehouse! It does create some interesting problems.
There's a lot of little things I'd could imagine being added (power ups like kill all odd numbers, maybe lift blocks below you, a hammer to just break a block you wanna break, lots of possibilities!), but I also really like it for what it is.
Great job!
