You won't find geometry dash on your average app store. It looks like a simple test of reflexes, but it's actually rather challenging. Imagine a basic Super Mario Bros. level where a relentless electronic rhythm controls every jump and tap. That sums up Geometry Dash, a game with an easy-to-understand interface but a very difficult learning curve.

At first glance, the notion seems straightforward. As you make your way through a perilous maze, you'll have the chance to use a cube and other forms that can be unlocked. The only thing you can do is tap the screen to quickly send the cube climbing. Nevertheless, a bewildering complexity lies concealed behind this apparent simplicity. Set to pulsating music, each level features a unique combination of spikes, saws, and gravity-defying twists. The key to success is a perfect synchronization of timing and response. A strange and pixelated dancing routine is the consequence of having to tap in perfect time with the music.

Geometry Dash's strength lies in its rhythm-centric design. The levels are turned into aural environments, with their challenges carefully crafted to match the beat and harmony of the music. A rapid series of spikes can be triggered by a powerful bass drop, while a soaring synthesizer melody causes extended leaps across deep chasms. The developer's mastery in sound design is on full display in the highest quality levels, which provide an effect reminiscent to interactive musical films.

However, Geometry Dash brazenly displays how difficult it is. Because of how challenging the stages are, players risk losing all progress with only one slip-up. When your perfect performance crashes and burns, the screen can explode into a shower of pixelated pieces, which can be extremely frustrating at first. Still, there's this strange allure lurking beyond the surface of this annoyance. Every successful jump, every completed section, is like a personal victory. To its credit, the game makes good use of the "just one more try" mentality, encouraging players to hone their reflexes until they're beat masters.
