In Little Space Duo, you play as a young girl named Lucy who was captured by an alien cargo ship after being wrongly mistaken for an Earth specimen. She befriends a small robot on the ship (which she nicknamed Sunny), and the both of them set out to fix things and find a way to send Lucy back to where she came from.

Players have to switch between both characters frequently throughout the game in order to solve some of the more difficult puzzles. Cargo robots that patrol the corridors must be avoided, else you risk being transported back to the start of the level and having all of your good work up to that point undone.

Save points can be found in certain areas as well, and they come in very handy whenever you feel the need to experiment with a couple of possible solutions for any puzzle segments.

There are five levels to play in this beta demo version. (source)
