Neat game! Seems pretty interesting so far ( I got back to the derelict ship for the second life), but you probably shouldn't have the option to skip the derelict ship still available once you arrive at it.
Also, it's pretty easy to soft-lock yourself in the first run by removing the food coupler before you finish fixing the ship, at which point you have to start over from the beginning because you won't have the food to get to the ship.
Overall, a fun game though! I'll be excited to see it become a full game, if you continue working on it.
