I don't think this game go through the basic play test, The level design is hard to grasp, making the game unecessary difficult, (like relicta) and when you must point a laser in the right direction you don't even see where you're at ! If you like the theme go for project temporality insteed.
Here, the sand, water, creatures are all based on the physic engine, and it is working just fine. But the most important, and pleasant in this little journey, is the sens of authentic life, there is a lot of effort in the ecosystem, the original creature behavior / design, and the world. Treat yourself : give you a nice trip.
