A good implementation of the Incremental Card Game genre! Well paced, good unlocks, forgiving but rewarding of basic blackjack skill, lets you count cards if that's your thing.
My small gripes are that the music track ran glitchily on my phone browser (not a big deal) and that successfully holding five cards isn't a win condition (I know 5 Card Charlie isn't a universally applied rule, but it's been in play whenever/wherever I've played IRL and I don't think I've seen it employed yet in an itch game. It has a nice statistically bad but intuitively tempting aspect when you're at four cards and holding a low stop point value like 16 or 17.)
