This is just a quick announcement to say that with the release of V0.21, I'm now happy with the amount of content within the game to warrant putting a price on it. As such, after the 30th of September, 2022, the game will no longer be free.
So, if you were on the fence about trying the game, this is your warning to grab it now while it's free! Everyone who owns it, (even if you've never played it as long as it's in your library), will keep the game after the price change. So if you get it now, it's yours to keep!
This also applies to those of you that already own it, don't worry, it won't cost you anything to keep playing and receive future updates. Hopefully by making this announcement and giving you time to get it before the price changes, no-one will be upset with the game no longer being free.
Edit: It appears Steam have removed the button to add the game to your library from the store page earlier than planned during the transition to becoming a paid game. Unfortunately this is out of my control and I cannot say whether it'll be back before the 1st of October, but it may already be too late to grab the game for free! I have no control over this I'm afraid.
