It's been almost exactly two years since itch.io decided to no longer allow me to sell my game through their native payment system. Why? I was never given a real reason. 
Over these past two years, I've continued to provide everyone who purchased the game here with the latest updates — even though this meant extra work on my part.

Now that the game has officially launched on Steam (about a week ago), I’ve decided to discontinue support on itch.io.
But don’t worry — everyone who bought the game here on itch.io now has a Steam key available in their library. You can use it to activate the game on Steam and receive all future updates for free there.
Please note: V0.18 will be available on Steam in about 3–4 weeks.

Thank you for your understanding
