I can't stop playing this demo. I play it at least daily, alternating between going to the basement and the lounge. I wouldn't call myself good at the game, but I just can't get enough of it. You've created something incredible here. I've been playing it for a while, now, and I really love how you've improved everything gradually; the animations, the balance in the costs, changed the progression so we have a choice of where to go, ordered the suits from hardest to easiest, and I haven't seen a single change I dislike.
I have exactly one complaint, and it's that The Moon tarot is... iffy with cards that steal it. It's very balanced when it's under your control, but if an opponent steals it (like the Manager, who's right after the spot where you'd get it), then they get to deal triple damage to you and you can't see your own cards. I'm not sure if this is intended to display the innate treachery of The Moon tarot (if it is, then damn) or if it's just a glitch.
I also have exactly one suggestion: maybe some post-game challenge decks would be fun! An all-arcana deck run, a run where your bust limit is 19, an all-glitch card run, a run with a deck where your only cards are double-backed cards and reverse/business cards, etcetera. I think it would be fun!
Thanks again for this phenomenal demo, I can't wait for the full release.
