A Block Too Many

The guest from space arrived at our planet in A Block Too Many not for destruction, but for creation and you can help him. The alien needs to build a tower of maximum height, as far as possible. Apparently he needs a building for some of his goals. An alien will use his blocks as building materials, which will appear one next to a flying saucer. Blocks can be moved in a horizontal plane to choose the best position for reset. To reset the block, click on the gap key in A Block too Many.
