About this game

Bielefeld, 1996. A phone call in the middle of the night, a voice like a piglet on helium – and suddenly you're caught up in the biggest fraud in human history. Run, jump and stomp your way through 30 levels, from Bielefeld's old town to Mexico and all the way to a base on the Moon.

OP-T (Operation TIMESAVE) is a classic retro jump & run with pixel graphics, snappy jumps and its own music for every level – made for touch controls on phones and tablets.

★ 30 LEVELS IN 4 WORLDS
• Bielefeld & the secret lab: office corridor, city centre, army barracks, sci-fi lab, parking garage and Bielefeld by night
• Space station Gamma11: sci-fi corridor, hangar, Bielefeld's old town and Sepal
• Mexico: Chichén Itzá, Mérida, Carretera 180, Tulum, the beach, the jungle and a cenote to dive into
• Outer space: command centre, flight to Jupiter, a space battle, the trip to the Moon and the grand finale at the Moon base

★ THREE TITAN STONES
Sina, Reta and Elda are well hidden. You can't leave the level without the stone – and every stone you find gives you an extra life.

★ JUMP, STOMP, SCORE
• Jump on enemies' heads: +100 points
• Collect coins: +10 points each
• Find a Titan Stone: +200 points and an extra life
• Reach the goal and your level points are doubled, plus a 100-point bonus
• But be nice to dogs – stomp one and you lose 100 points

★ BEAT THE CLOCK
Your best time and best score are saved for every level. Can you go faster?

★ CHANGING HEROES & ENEMIES
In a toga, a uniform, swimming trunks or with a diving tank: your character changes with each chapter of the story. Along the way you'll face soldiers, scientists, gangsters, lizards, spiders, pesky mosquitoes and a safari man who doesn't give up easily.

★ SIMPLE CONTROLS
Three buttons: left, right, jump. Through the door, into the pickup truck or aboard the spaceship – the next level is already waiting.

★ FAIR & EASY
• Free to play, no account, no sign-up
• Your progress, best times and settings stay on your device
• The game remembers where you left off – just continue later
• Playable in 12 languages: English, German, French, Spanish, Italian, Portuguese, Polish, Russian, Chinese, Japanese, Hindi and Thai

★ BASED ON THE NOVEL
OP-T is based on the humorous science fiction novel "Operation TIMESAVE" by M.A. Jundt. You don't need to know the book – but if you read it, you'll recognise many places and characters.

Everybody knows Bielefeld doesn't exist. But if it does, that's exactly where the universe starts falling apart.

Note: The game is funded by ads (a banner in the main menu and an occasional ad between levels). After a game over, you can choose to watch a short video to get an extra life.
