If you don't know Submachine, this is a point and click puzzle journey into a surreal, slightly philosophical world of layered reality and fragmented locations across time and space. It's easily one of the best works to come out of the flash games era, all redone with beautiful hand-made illustrations and designs, and the 14 chapters all flow beautifully into each other. There's no moon logic puzzles, there's no obtuse riddles, just reasoning and an insane amount of locations to explore. TAKE NOTES, you'll be thankful.
If you know Submachine, this is the entire saga, including Network Exploration, all redone, cleaned up, improved and integrated into a very big, very choesive narrative and gameplay experience. All of Submachine, completely improved. There's a fair amount of new content too, particularly in the Network Exploration, there's SO MANY new rooms and puzzles, it's been turned into a more classic puzzle game, just on a massive scale. There's so many room.
This was a wonderful experience, very rewarding to the end.
