For anyone struggling with this game, most of the things that can be interacted with need to be spam clicked before they react. Except the ones that don't. Also the hints are more just puzzles that directly tell you what the current card is when solved. Except the ones that don't.
That's my main gripe with this game, often you don't even know what you're looking for. The solution and hint do not follow any pattern that I can determine, they are completly unconstrained. One even uses audio, another the keyboard. The hints in the dialoge really are too vague for how many options you have.
