Snake Pit: door won’t open. Watched walkthrough to see exactly where to tap.
Sometimes when I’d tap door, game would zoom in on a spot not even close to the door, at bottom right.
Linked Room: coffee pot clue is impossible to see. Had to watch walkthrough to get the numbers.
Hamlet House, arrow puzzle doesn’t work. Yes, I know the cigarette is needed to solve. Watched walkthrough to be sure I had solution right. I did.
Still very worth downloading this bundle of games. Just a heads up though, in several games some things were so small, impossible to solve without walkthrough. I hate using walkthrough because you see solutions to other puzzles. I like to try solving things myself.
