Cool game!
i played one day to learn the mechanics then restarted and went trough two more.
It feels like you can easily snowball out of control and the game becomes tedious? I got Anal, Spread Ass and the card that Burns from your hand, that was enough to trim my deck down to its best cards quickly, then the level-up upgraded those cards. The last rounds of the second day were just putting the cards in the slots, I had won already but I was incentivised to keep grinding for exp and coins. I think the way to fix this would be to make clients more difficult after you reach the minimum goal? It wouldn't solve the tedium but it would reduce the snowball effect.
There is an issue with LOVE: the game autosaves at the start of the turn but not after the combat finishes and LOVE is awarded. You can return to menu and load the quicksave to finist the same day and get LOVE again.
