Really enjoying this! But have found myself wishing for a control to "peek" at cards behind, since mouseover behavior seems inconsistent (e.g. to look at prior answers in the wordle solitaire).
Also wish that werewolf solitaire allowed for partial guesses while deducing (e.g. if you've narrowed down that it's a club but not sure if it's queen or king).
Will post other things as I encounter them, but this is awesome work, you really should post this to steam!
