Starting with 14 June 2021, new players will have to buy the game. If you already have it in your library, this change will not affect you in any way. And if the game is on your wishlist, you have 7 days to claim it for free. Hopefully, this measure will help me to fund the development of my new game which is still going on but not as fast as I expected.
All the best,
Eugene Zubko.
