We've kept the last alpha build we made available to play here. We've since moved to beta (on Steam) and a release candidate. You're welcome to give this alpha build a try, but you might encounter bugs we've since solved since this build is no longer supported. Also, be sure to check out Powargrid on our Steam store page.
What is the Unity Web Player?
Unity is the game engine we are using to build Powargrid. The Unity Web Player is like the Flash Player plugin, allowing you to play games directly in your browser. For now, this is the best way we have to make sure Powargrid runs as smoothly as possible for everyone who wants to try it. It also means we're able to show you the game that much sooner.
