This is a puzzle game wearing an adventure robe and its great!
Its better than just going from a flat puzzle screen to the next puzzle screen because you are more immersed in the world. They also mix in monsters, lasers and flame throwers! Many of the early puzzles are easy, but there are definitely more challenging ones as you go on. The company said they will add more puzzles with updates.
Ive not had any problems with crashing. Im playing on an ipad2.
