Ever wanted to solve puzzles that literally twist your brain? Exit DS delivers exactly that kind of mind-bending challenge. Based on the popular board game series, this little gem asks you to escape from increasingly complex rooms using nothing but your wits and a keen eye for detail. What makes this game truly special is how it utilizes the DS's dual screens to create puzzles that feel genuinely unique to the platform. You'll find yourself rotating the DS, blowing into the microphone, and using the stylus in ways you never expected.

The graphics might not blow you away at first glance, but they perfectly serve the puzzle-solving gameplay with clear visuals and subtle hints hidden throughout each environment. The soundtrack creates just the right amount of tension as you race against the clock to escape each room. There's something immensely satisfying about that "aha!" moment when you finally figure out a solution.

Exit DS earns its place in any top DS games list because it embodies what made the handheld special - games that could only exist on this unique dual-screen format. It's the perfect pick-up-and-play experience for commutes, with puzzles that are challenging enough to keep you engaged but not so difficult that you'll want to throw your DS out the window.

Glory Days 2 is a hidden treasure that blends side-scrolling action with strategic elements in a way that's surprisingly addictive. Set during wartime, you control various vehicles like helicopters and tanks while simultaneously managing ground troops and resources. The real kicker? You can reverse time to correct mistakes - a mechanic that was ahead of its time when this game launched.

The controls make brilliant use of the DS touchscreen, allowing for intuitive management of your forces while navigating the battlefield. The pixelated visuals might seem simple at first, but they're packed with character, and explosions are particularly satisfying - little bursts of pixel-perfect chaos that light up the screen. Sound design deserves special praise, with the whirring of helicopter blades and rumbling tank treads creating an immersive battlefield atmosphere through those tiny DS speakers.

What puts Glory Days 2 on any respectable top list is its unique blend of genres. It's not quite a shooter, not quite a strategy game, but something uniquely its own. The difficulty curve is perfect - easy to pick up but challenging to master. You'll find yourself saying "just one more mission" as the hours tick by, especially when experimenting with different approaches to each level. For anyone who appreciates games that don't fit neatly into genre boxes, Glory Days 2 is an essential addition to your DS collection.

The pixel art is gorgeous, with vibrant colors and charming character animations that squeeze impressive personality out of limited resolution. Each world introduces new visual themes while maintaining a cohesive style. The soundtrack deserves special praise – catchy chiptunes that'll have you humming long after you put the game down, perfectly complementing the retro-inspired visuals.
