The visuals are nice and so is the sound design, but there isn't really a 'game' here. This is an exercise in trial-and-error as well as memory. If you've failed to upgrade some odd skill that you've never used before and have been given no warning was important, then you die and have to load a save to try again. Some might say that this style of game was good, but when all the effort can be completely removed by keeping tracking of what skills you need and when you need them, it becomes utterly pointless. So... not a puzzle game, nor a sim-game, but a memory-training game. I regret spending my money on it, since I went into it under the impression it would provide more depth than a paddling pool.
