Yeah, the game is definitely designed to be played with a mouse (or gamepad) and would be a challenge on touchpad.
I have a ton of deckbuilder experience personally, so to me discarding cards from your deck being OP is a pretty natural thing, but I’m sure it’s counterintuitive for players who are less experienced in the genre.
About card descriptions, it’s not so much intentional, and moreso that I wrote them all at 4am on the final day after adding most of the actual game content + playtesting + balancing etc :’)
Glad you enjoyed the game!
