Noobsource Review:
„The mechanics are familiar to other cookie clicker style apps such as Make It Rain, but there some features that seem to set it apart, if slightly. You can build a fortress to hire warriors to send on a quest when you have enough wood to build a quest tower.“

„So, is orcs a game you should play? Well if Make it Rain is your kind of game, this is worth a shot. After speaking with David, there are new features coming in the next few weeks to provide some much needed motivation to keep playing such as raiding human settlements to prevent them from tearing down yours. „
