This game doesn't offer anything you couldn't get from an online point-and-click game without paying $5. In fact, it offers less — I've played online point-and-click games that are far more fun, challenging, and interesting. The only thing this offers that many online point-and-clicks don't is a 3-dimensional setting, and that's not exactly a huge selling point in a genre where aesthetics is at *best* a secondary focus.
I also recall having trouble with the opening screen, where I found I could not type certain letters. I believe I also saw some things that were in French. That strikes me as rather sloppy.
Lastly, I discovered that the help system is awful. I used the feature on a puzzle that I couldn't figure out for the life of me. Firstly, there was no option for a mere hint or nudge — I could either do the puzzle myself or have the game do it for me. That's bad enough, but worse, after I used it, I could not go back to that room now that it was solved, so I couldn't even see what the solution was!
Some of the puzzles were good, but I don't even remember them anymore. I found this game very forgettable. Upon finishing it, I had no interest in buying the rest of the series, because why would I pay money for more of this when it doesn't even compare favourably to its free counterparts?
Save your money and go play something that's at least imaginative and intriguing, like Submachine — or if you insist on parting with your money, try Inbetween Land.
