THE FUTURE!
Small updates drop monthly on the main site. For big updates, those are chosen by the subscribestar supporters. The latest poll should give you an idea of things that are likely to get added in the future. Elves and Spiders are both guaranteed updates. The rest are fully up to the player base to support. This poll will run until the end of December. Whichever option gets the most votes will be the next big update I start.
