Nice Balatro like.
It works well, which is impressive. I won't comment on the polish, as it's clear how hard you worked on the mechanics. I still feel that you could have come up with a much simpler idea that centred on the actual theme, given what you're capable of. A 4 day Balatro clone is a tough task. Scoping is crucial during game jams. Yes, Balatro technically has "looping", but I think you know it's a bit of a stretch :P
