Background scenes and the diving gear look alright. There's room for improvement for other hidden objects and plates.
Game play is generic. One has to flip some switches and collect items (e.g., symbolic icons, amulets, and hidden crystals) for unlocking safes. There are a few easy puzzles to solve. You just have to find a relevant clue card. The diver equipment is a nice addition to the game, but you only have to find everything and use them once at the end.
