The new Indiefort Countdown Bundles are giving funds to my friend's brain cancer fund for the next five weeks.
The Indiefort Countdown Bundles will give 5% of its money to help my friend (and great fantasy artist/DM) Daniel, with the option to give as much extra as you please to Daniel and/or the devs. There will be a new bundle every week, with discounts going to people who buy them each week (thus the countdown moniker).
You can see a list of games in the bundles here.
