Alone in Space

This is a first person action adventure where you wake up in a pod in an abandoned space station on a planet being terraformed. You have to traverse the many halls and corridors, solve puzzles and figure out what happened to the crew and why you were left behind.

You can pick up items in sort of a "Last-In, First-Out" inventory (i.e. it stacks) to solve some puzzles, while other puzzles require you to rearrange wires, replace faulty electronics, solve power redirection puzzles, and so forth. It's not an entirely casual experience as you can die of environmental damage such as being zapped or from lack of oxygen. However, there are no monsters or robots of any kind.
