I'm sorry but I could not figure out the game for the life of me. I only got one block to stay and nothing would happen after that. The music also felt out of place.
You have to click the black hole to get new blocks :)
I did but the blocks wouldn't stay where I put them.
Now i understand your issue. Every block has to be set at the bottom. if you already set a block, next one should go under it.
