Very cool game, several hours into it and not what I expected at all.
fyi for me the mac app in the zip didn't do anything, so in case this helps anyone with issues to run this on a mac I had to:
1. install renpy, use renpy to create a new project
2. unzip Price of Power, copy the "game" folder over the "game" folder in the new project. then you can open the new project and it will run.
