Perhaps should consider splitting this into a Disambig between WMW2 and WMM

Hints were a feature in Where's My Mickey? and Where's My Mickey? XL which helped the player complete levels. Once a hint had been used for a specific level, no new hints would be used when accessing the hints for the same level. The player started out with 2 hints given for free and more hints could be obtained via In-App Purchases in sets of either 5 or 20.
