how do i download
When you click the "Download Now" button, it will give you the option to either just download the game for free by clicking "No thanks, just take me to the downloads" OR pay us however much you feel like paying us for the game, if you feel like giving us money.
The "free" option isn't immediately noticeable (I've circled it here to make it a bit easier to see), but I'm not sure if we can change that.
