Ok now, saying it's a Joke is disrespectful - if you cant justify the cost of the full game, then get it on Patreon for $12 and then as the game is updated and released, spend another $12 if you want to continue. $12 is around 2 cups of coffee where I live, and I've spent a lot more time playing the free version than I would have enjoying the same value in coffee...
From what the guys have mentioned, there's around 2000 400+ subscribers on Patreon now, so it would seem many guys have thought it worth giving it a go there.
