This game has you star as the dashing captain of a time-travelling ship piloted by a helpful Mother AI. An enemy faction is travelling to the past to sabotage your present, and you have to stop them.
There are 4 or so main time periods you travel to, each with its own set of puzzles as well as some recurring characters. Names of things in the game are often references; one whole area is a giant reference to steins;gate.
In between those areas, you can explore the large ship you pilot, with several crew members who can help you can give you advice.
The game has few bugs, although I did lock myself out of victory once by returning to my quarters before I finished a section, triggering a cutscene too early.
The story has good story beats but felt a little less descriptive in the middle, possibly because the author could vividly picture things due to the references but I couldn't due to not knowing the games.
Overall, this is a substantial game and I played it here and there over several nights.
