We're glad you liked our game <3
We had plans to make bigger buildings like skyscrapers and upwards moving screen, but the debris pile was way too much since they piled up on top of the houses to be built, also we concluded after play testing that bigger buildings would prolong the game play per session too much.
We do have plans to continue on the project to make more variety, including separate cities and bigger buildings as well as more building pieces and a level editor.
