I've started a series of Dungeon Pixel Packs that I'm selling on the Scirra Asset Store. I'm aiming for high quality at an affordable price, and I'd also like to get the community involved in helping me shape the future of the packs.
The first pack, Iso Dungeon Basics, is available here, and contains the necessities to build your own dungeons.
The second pack, Dungeon Enemies, is currently in development and I need you to get involved to tell me what you'd like to see in the second pack! I've set up a Google Form for you to tell me what you want to see in the next pack, or alternatively you could post a comment here letting me know your suggestions!
