I put a link to the discord on the game page up there.
How long it took? Hard to say because this game was built on top of the previous Fear & Hunger game, so many of the features were already there. Only graphics and new enemy behaviour had to be made in those cases. I think the game has been 6-8 months in development, but the development has been overlapping with the updates to the previous game, so.... it's a bit hard to say really lol. I'm glad you like the stuff. It's good to know the details matter, because they certainly require more work.
