The download link at the bottom of this page should work: http://mattcarr.itch.io/paint-the-town-red
If it doesn't then try a different browser. Alternatively (and preferably ;) ), just wait another few days for the full version to be out on Steam here: http://store.steampowered.com/app/337320. It's somewhere in the order of 100,000 to 150,000 times better.
