I sat down and played through in a single quiet day. The game was engaging and had a good sound track. I liked balancing the ecosystem.
Couple of points: character development? Why are these two weirdos all alone on Mars? One Asian grandpa whose facial expression never changes and an all-smiles girl who is dressed for the mall? The computers intentionally messed up syntax grated a bit too.
Otherwise an attractive, challenging platformer with a nice Martian twist. Give it a try.
