Tonight I released a free version of Maze Escape so I can expand my audience and try using ads. This development effort took a lot less time than I thought - I hardly spent a day to complete it. The hard part was getting the ads into unobtrusive, yet visible locations within the app; I don't want someone to go for a button and suddenly have an ad appear in its place.
I hope a wider audience enjoys Maze Escape and finds it in themselves to pay for the ad-free version.
This does not change my plans for updating Maze Escape; all updates I have promised so far will be added to both versions. After that, I may make some updates exclusive to the paid version.
