Hi Ago! Nice to have you.
I'd like to suggest some more details on your demo version, won't hurt. Pics scream 'nothing smells like threesome in the morning', to screw a reknown film quote.
A 'post-apocalyptic' scenario sounds quite fine, perfect for rpg elements to include. You could tell a bit about the background, open a thread and post more pics. And maybe develop some more if you think you should still add content, and later present your game here, so ppl have sth to discuss. Plus you may collect plenty of good ideas from users on the way, for the next parts.
Have fun and cya around.
