Glitches and too long to build and too expensive

This is a decent game, however, takes too many crystals to rescue the animals from various islands, takes too much coin to build a house for the animals.
Far to few crystals can be found when searching islands. Little coin is found as well and/or given.
As well the swipes better options need to be available, too few crystals found during swipes.
