Been a listener for a while, never registered for the forums (until now) to finally contribute back!
In the latest podcast (episode 292), the guys mentioned making an archive/redirect website for Wizard Jam, and I decided to make it myself! Well without further ado, the website is located at: http://www.wizardjam.org. The main page will automatically redirect the user to the latest itch.io page (in this case, for Wizard Jam 4). To access the simple archive page (I promise I'll make it prettier soon!), simply head over to http://www.wizardjam.org/archive/.
I hope this can come in handy for you Thumbs readers!
N.B.: If any of the hosts of Wizard Jam (or Idle Thumbs hosts themselves) would like access to the GitHub repository that the website is hosted out of (using GitHub Pages), send me a PM!
