Some players buid skyscrapers, but it's notoriously broken, yeah.

When returning to the game, one may easily forget that each time a piece is added, the whole structure is recomputed, and this can take several seconds. If you defocus too fast, you can think last focused piece was blue or green, whereas it is orange or red after computation!

I've had buildings where a blue piece is bordered by dark red pieces. It's real buggy.
