We are currently working on a free DLC to release on Halloween, it is going to be themed around horror (but not too much) and based on the binding of Isaac.
It is going to feature
-a new tile-set
-3 new mobs
-more lore
-more achievements
It is a way to say thank you for the people that supported us on release.
We are also working on more free content besides this one so stay tuned.
