I think a few smaller, easier levels at the front would be good. I'm not great at minesweeper (I do enjoy it though), and I couldn't get past level 2. It feels like unless I get a good start, I'm screwed, because then I'm just clicking around on random spots to find a safe area and there could be a bomb anywhere. That's the fault of Minesweeper though (or me!), not Swope. 😂 I tried the easy difficulty, but still could not get past level 2. I couldn't bring myself to try immortal, probably because I can't allow myself to not suffer.
I have never played Balatro, but I've seen videos of it, and I think you did a good job of saying "This is Balatro Minesweeper!" with your graphics and layout. It's nice seeing it checking all the tiles at the end of a level and adding up my score. I liked it, and I would play more of it.
