Gatamari Escape 25
You blacked out while hiking and woke up in a lab-slash-prison of some sort, and those men guarding the exit probably won't let you by peacefully. As the introductions of Gatamari escapes go, this isn't one of the more elaborate ones, but it certainly serves the purpose of setting up Gatamari Escape 25. The song and dance is a familiar one: click the direction arrows to move around, click on things to examine and interact with them, solve puzzles and crack codes, and hope you'll see the light of day at the end. If you get stuck, use the handy save feature and come back later. Oh, but don't worry: just because the dialogue and descriptions are in Japanese doesn't mean you'll need to learn the language to make any progress. Gatamari is good about that.
The country of Japan breeds some fantastic room escape developers, each one with its own definitive style, and Gatamari is certainly one of them. G's escapers involve simple yet effective graphics, intriguing and immersive atmosphere, mostly-linear yet never-too-restrictive gameplay, and most importantly, fantastic puzzles. The puzzles in this room are well-designed, making sense when you think about them correctly without being completely transparent, and you can usually tell which clue goes to which puzzle when you've seen them both. There's no changing cursor, but every spot worth clicking on is intuitive. There are some obtuse moments, but only because they aren't tricks Gatamari usually pulls: there's one puzzle that needs a little bit of brute force to solve, and another that requires you to wait around a bit at a particular view. All in all, just like 24 or 23 before it, Gatamari Escape 25 is a fantastic puzzler guaranteed to keep the player's mind busy. It took me half an hour to make my escape, and with the better ending of the two... how long will it take you?
