Promising game system, fun to play with even if it is regularly difficult to get much past floor 10. Could do with some quality of life improvements, like being able to look at your whole deck when choosing what cards to add, and a settings screen to adjust volume or even be able to quit the game without right clicking the app on the start menu. Would be interesting to see this more fleshed out with a larger variety of card effects, and perhaps enemies which also used more interesting tactics to be harder to beat rather than simply stronger/tougher.
