dEXTRIS offers a challenging and fun time at the cost of your eyesight!
David: dEXTRIS may sound a bit like Tetris, but gameplay is a lot different from what you might expect. Although there are blocks involved, dEXTRIS plays out more like Flappy Bird than any iteration of the classic game that you might remember. Quick reflexes and tons of practice are required to even go past the first level, and this guide will help you improve your progress by leaps and bounds.
WP - "dEXTRIS is a new endless puzzler game for the iOS and Android. Despite the name, dEXTRIS has no relation to Tetris. Instead, you have to go as far as you can while making the blocks move in the correct directions in order to avoid spikes and other obstacles for as long as you can."
