Okay, I confess. The title is misleading. It is unfair for dEXTRIS to be compared to the infamous Flappy Bird. And aside from the cube(s) that appears in the game, nothing in dEXTRIS resembles anything from Tetris. In fact, my initial dislike of the game quickly turned into like. It's a game that deserves to be praised for its own merit, not attacked for any unjust comparison to other games out there.
In dEXTRIS, created by Chaotic Box, you navigate a twin-cubed object (or a spaceship, because it looks like one), avoiding spikes, as it makes its way across the space to an unknown destination. The controls are simple: tap left to go to the left, scraping the metallic edge of the course, tap right to go the opposite side, tap nothing to remain at the center, and tap both sides to split the two cubes of the spaceship to the left and right. There are no coins, power-ups, or any bonus items to collect, which can be nice additions to a future upgrade, keeping true to the game's simplicity. Go as far as you can, increase your score, and beat strangers in the Leaderboards.
Getting the hang of the game was infuriating in the beginning, which lead to the Flappy Bird comparison (again, my apology). Once I got it, I made it further and further eventually (though as of today, it's nothing to brag about). The graphics is nothing groundbreaking, it's no RoboCop nor Monument, but it does its job: make the game pleasing and easy to the eyes, and make it challenging. I say challenging because as you get farther, your spaceship accelerates. The background moves too. You may not notice it right away but it changes, adding to the level of difficulty in the game. The music and sound effects fit well, especially the scraping of the metal which can pose a problem to some who gets chills or goosebumps with that.
dEXTRIS is an addicting game, one you can use to quickly pass the time or invest a lot on to satisfy any personal agenda. It's simplicity is its strength, and reminds you of those early 90's games, where goals and gameplay were simple yet the entertainment and replayability were high.
Oh, let me add. dEXTRIS' icon showed a menacing skull, yet it was nowhere in the game. A bit misleading but the game is still worth it.
Pros: Simplicity and high replayability.
Cons: No missions or challenges to give goals to players.
Summary: Simple and entertaining are best adjectives to describe dEXTRIS. A “classic games” nostalgia factor is in the game, and there is a lot of room for expansion (which I strongly believe will happen in the future).
