Hey!
You could do a clickable overlay game (you’ll need plenty of overlays tho.) You could have the character need to find them in a specific order, or just find all of them, etc…
You could also do a game where there’s door requires a passcode to get out, and the character has to find clues to figure out the code.
You could also do a “direction” game, where you allow the reader to have the character go left or right, and in order to get out, they need to have the correct sequence (i.e, Right, Left, Left, Right…) and so on. If they get it wrong, they have to restart.
There’s some more ways to do it, but those are a bit more common and easier to direct. Hope this helps!
