Rusty Lake Universe is expanding~
As with all games from Rusty Lake, Underground Blossom centers around a character from the wider Rusty Lake Universe, in this case, Laura Vanderboom. In the game, you’ll visit various stops on a train line, with each stop representing a major part of Laura’s life, both from the past and events from her potential future. You’ll need to solve puzzles and determine the correct route to take that will uncover one of Laura’s timelines, while simultaneously helping her make sense of her life and escape the corruption of her mind!"
And if you want to get better acquainted with the history of the Vanderboom family after that, there's a nine-game Cube Escape bundle on Steam for a very reasonable price.
