Needs much more, seems like something that only took you an hour, my WIP app has been under construction for at least 1 and 1/2 months.(off and on)
I don't think the builds need to be gigantic, it just has to be clever.
I like the build but maybe something more..."moar".
Anyhow good luck.
Im making terrain, and Im not duplicating one row to make a cliff, im laying every single brick seperatly. Shaping it the right way takes time, and I can only get so much done. Besides, after Im done with the terrain Im making buildings on it as well, which will take just as much time.
