I have not set up a discord yet. I am waiting to get closer to a Beta. Then I planned on setting that up and creating a Steam page and finally a Kickstarter (or something similar) to get funds to advertise and buy some sound software/hardware. That is a good idea to release the sprite sheets though. It wouldn't be hard to do.
The missions I put on hold until I finish the leveling/xp/unlocking system. I've honestly have it half done, but I keep getting distracted with stuff in my 'real' life :) I have the 'script' written for probably 6 more missions and lots of rough ideas for others. The Anchor Rage missions will end in maybe 3 or 4 more missions and then it will switch to a new city (the Karkadan). This will be a whole lot of new art assets to create (Straw mats, bamboo/stick walls, dirt floors, totem, cloth type pendents etc. Think Native American and Inuit decor. Also they live in less sandy and more dirt/rock so the default sand background will need to be switched too for their area.
