After finishing the other games in the Submachine series, I tried this one and it's really interesting. I've never played a game quite like this one. The game starts with little information is given to the player, and they have to discover codes in order to branch out to more areas of exploration. Not all of the codes are given to you in a simple numerical format, and other puzzles are quite challenging to figure out. I've written down two pages of notes in a notebook keeping track of codes and information I come across, and I still haven't reached the game's ending, if you are wondering how much there is to find in the game. I rate it 5 out of 5 stars, really unique point and click game.
