I really find this app easy to use and fast on map making however I feel that charging people $0.99 for five extra tiles is asking a bit much since the app its self was $30.00 and if I were to buy all the extra tiles, it would run me another $10.00 or so...
Either way, one suggestion I do have is a clean up of auto sorting of the tiles... Its to messy coming from the first Battle Map.
