The music pulses, as does the screen. The bar moves to try to distract you. Text appears in the background. "Hello." "Do you even read me?" It tries to get your attention pulled away from the bar.
Gauge is a very simple game. There's a bar that fills with color when you tap the screen. Hit the ends of the gauge, though, and you lose the game. There's a sweet spot near the end that rapidly fills the gauge, eventually introducing a second level in the gauge that fills, too.
But the game works against you, introducing distractions and pumping up the music to see how well you stand against them. Gauge is a psychedelic game. The screen changes colors. It shakes, and turns into lines to try to confuse you.
It's fun, it's addictive, and there are different modes for you to challenge yourself with. Plus, you can try it out for free.
