Hi! Since our original demo release in 2020, we have enabled the option for players to donate. It is appreciated by not required at all, and you can simply choose "no, thanks take me to the downloads." (If this option is not showing for you, please let me know and I will get that sorted out.) It's unfortunate that itch.io is very tricky with their placement of the donation button and I wish that it was less deceptive.
As a small studio led by myself, this project has been self-funded for many years. I did not know if I would launch a Kickstarter, and it was only going to happen if we felt far enough in development, which is now. Donating on itch.io has no relation to the upcoming Kickstarter.
I hope this response clarifies the situation for potential players. I stand by the notion that demos should be free and that was the intention of the Garden of Seif demo, so I hope this doesn't make anyone feel inclined to donate.
I want players to have the option to freely play the demo and see what it has to offer because I think the demo as is will show that the full game is worth purchasing.
