First, please download the MorePoints-EarlyAccess.zip package. When you unpack it, you will find builds for Windows (MorePoints-EA-Win.zip) and Mac (MorePoints-EA-Mac.zip, surprisingly enough). Unzip the one you like more (however, it might be helpful to pick the one corresponding to your operating system).
Open the executable and enjoy becoming THE Almighty Wizard*.
* Note that this is early access, and although we did our best to make our game perfect, the crazy 48h deadline could have caused some unexpected... features. Anyway, enjoy! :)
The version on Dropbox will be updated (there might even be hope for a beta!).
