I've noticed a lot of people everywhere, even on this forum looking for more from Hammerwatch. The main game was fun, but there is so much potential in this game. The main developers don't have a readily found twitter, or FB. They don't talk about the game much, and frankly I think the community is looking for them to say more about what is coming up, other than "We have more Ideas." and "More is coming".
I hope that they would take some time and post, something, somewhere that they are still invested in this game and making it's tools more robust. If they are not, there is a strong community that would like to take the reigns of the game and make some more in-depth edits to the source.
