The game features, yes, a pixel robot character, and the goal is to make the little guy jump vertically as many times as you can. The catch is that he's jumping inside a moving circle, and there's a gap in the circle, so you have to time your jumps carefully so that he doesn't jump through the gap, thus ending the game.
This YouTube video gives you a very clear idea of how the game works.
This game is made by Universal Games Team, and I asked them if there was anything in particular they wanted readers to know about it. They replied, "Pixel Robot Jump Saga is an insanely difficult retro game with pixel design and vintage sounds, making Flappy Bird seem easy."
I have to agree about the vintage sounds; listening to the game reminds me of my old Atari system in the best way possible. :) And the ease of the game--you just tap to jump--reminds me of old-school games, too.
I also asked the team what makes the game fun to play, and they said, "It's a frustratingly addictive game, an almost impossible game where you must tap to help a robot jump vertically out of a rotating circle and help it get back in safely. Just test your reflexes and see if the highest score you can obtain exceeds a single digit--you'll be a master if you get a two-digit score."
Have you played a game like this, where the creators say it will be hard for you to break into two-digit scoring? Sounds like a worthy challenge, if ever I've heard one!
