"Retry" is an upcoming game that is so difficult it will make you feel like you've "stepped into an 8-bit time machine."

Angry Birds developer Rovio Entertainment has announced a new game called "Retry," which bears similarities to the hugely popular (and no longer available) Flappy Bird.

Retry is described as "a game so hard, so addictive, so old school that you'll think you've stepped into an 8-bit time machine and gone back to 1986. Totally rad!" Like Flappy Bird, Retry challenges players to fly through a level without colliding with objects. "Fly. Crash. Repeat. It's called 'Retry for a reason," Rovio says.

Retry is available now on iTunes in Finland, Canada, and Poland. There's no word yet on when it will see a wider release or if it's also coming to Android devices.

The game is released through Rovio's new "LVL 11" publishing label. Rovio executive vice president Jami Laes told PocketGamer.biz that this new experimental publishing arm was established for games that "don't necessarily fit the normal thinking" of what gamers might expect to be a new game from the makers of Angry Birds.
