The Vacuum

In The Vacuum, a science-fiction point&click adventure game, you play as a college student, Leo, who has booked his trip home on a cheap cargo vessel together with his girlfriend Averie. Soon what looks like an uneventful trip takes a drastic turns, as explosions shake the ship. Everyone on board is a suspect, but nobody has a motive. With no other authorities on a cargo ship in the middle of nowhere, somewhere in the nebulae between Whitefall and Aberdeen, Leo must begin investigating.

Depending on how successful his investigations are, he will be able to find out about the mysteries that led to the explosions, who is behind them and why they happened in the first place. Whether lives will be lost or saved, justice will be served or not, Averie will leave him or stay with him, is up to the player. It is recommended to play the game at least twice, as it is pretty short and there's a huge chance you will encounter a completely different ending based on the choices you make during your investigations.
