I just created an account to comment. This is the first card game I played and it is so much fun. I beat it around 6th or 7th time. Having different strategies just tickles my brain.
The only problem I faced were I mistakenly restarted the game by pressing ESC (my habit actually) and a bug where you can unlock a door multiple time (by actively unlocking the door more than once). That slows down the game like a turd and somehow made the next door to have multiple locks (to which I cannot proceed).
Overall, really fun. Glad to have something really entertaining for free for a change.
