Wow! Amazing job. I'm a sucker for card games, so this was right up my alley. The gameplay is great: it takes a familiar matching concept but turns it into a really fun and well-developed system. The great variety in mechanics keeps it interesting and there's so many nice small touches like cards being partially obscured by the walls.
The art is fantastic as well. Thanks for uploading that concept art- it's really interesting to see that. I was surprised that this wasn't assets because the art looked so good. The art, lore, and audio combined make for just a great presentation overall.
The post does mention that the offline version is more stable, so maybe this only affects the online one, but the moon stopped changing for me. I didn't end up knowing how much time I had left. I wish I could have clicked the cards more often, too. I'm sure that's an intentional design choice to avoid people from click spamming. But, personally, I think I would have preferred being able to click more often but in exchange having less time before distributing food again.
I could totally seeing this expanded upon and being a game I would definitely get :)
