As you can see, we have the Support our Patreon button here :)
I will answer now without taking another look so sorry in advance, but I expect the demo (there was one?), to feel short. Depending on how long the game is supposed to be I hope you update the demo up to a good size to get a good feeling and make an announcement once it's done or something, if i use patreon it will be once or twice I can't stay subscribed sadly that would be to much in adition to everything. Thank you again.
