Hey, thank you very much for playing - and for the feedback! I guess we should encourage people more to make notes (e.g. on paper) for the game - like scribbling down the map, and what each potion and scroll does (if you find out). ;) The game is pretty short in general, so we wanted to enforce some kind of exploration.
Regarding the bug - interesting, never had that before. (The situation on the screenshot doesn't look unusual either.) If you or anybody encounter this again, maybe try to open the developer tools of your browser and look if there's some message in the console. If yes, I'd be happy to have a look at the error message.
Interesting indeed..... I'm pretty sure that's the exact bug that I encountered the first time I played (which was like, a couple days ago maybe?).
It's like the cards get randomly stuck in the middle of the screen for whatever reason (or atleast in my case, they were in the middle of the screen). I think it happened when I pulled the stomach card into the inventory slot. Either that, or maybe I was moving all the cards around too fast for the code to keep up; while I was trying to figure out how to play the game.
But yeah, you can look at the cards, but you can't use them in any way and you can't pick up new cards. It's a pretty game breaking bug. That can get fixed by reloading the page again, but then you'll lose all progress.
