You Can Only Build Up

A small prototype of a "city-building" game where you have to defend against alien attack! The higher you get into space the more aliens will attack you. You can build up infinitely high, but you are limited in width.

I didn't have enough time to really execute this idea as I wanted, or to add any real polish, due to other commitments. It is playable though!

Made for #Krassjam November 2017, theme:

"design cities and the sky isn't even the limit"
