Great game, much crashing – Doors & Rooms: Escape games Review

The difficulty level for this version is perfect -- challenging and logical. It could be fun to use with students in a classroom. However, the app keeps crashing. This makes it frustrating to have to re-solve parts of a puzzle -- the fun has gone and then it's just drudgery. Please resolve !
