I recently played through this. It's basically an extremely bare bones version of platforming similar to Prince of Persia with a ton of mini games (QTEs, timing your button presses, memorization, etc.). You can get the full 1000 achievement points with 5-8 hours but there's a lot of item collecting to do. There's five levels and feature sequences and minigames that are unique to that level such as making your way through a huge sand storm or outracing an avalanche. There's not too many games in the "survival" genre out there and may be worth picking up for $5 or $10.
