remix this, and change stuff like the wrecking thing. fidget with the motion to make it look realistic. press "c" to create a new tower. the first one has been done for you already when you click the flag. press "d" to watch your tower get destroyed by a big boulder ball thing, the blocks will go in different directions, fall, and then they'll be deleted.
just fidget around with the simulator. nothing too hard or much. the game's actually pretty boring in my opinion if you just press "c" & "d" like 6 seconds after each other. if you keep pressing "c" and "d" for a long time, one by one very quickly, it'll look satisfying. in this project turbo mode is just wrong.
