Ruthless Safari is an endless runner that has you jumping over cacti whilst being hunted by a lion. So basically the Dinosaur Game without the ducking feature. That's it.

Instead of continuously gaining score, you accumulate kilometres, which slowly increase over time. The main goal is to reach 100 kilometres, for the final achievement, which should take you 15 minutes, if you make no mistakes. That's literally it. Constantly and mindlessly jumping over cacti for 15 minutes.

If you want to get this game for the easy yet mind-numbing achievements, wait for it to go on sale. At full price, it is a literally a scam. If you aren't an achievement hunter, avoid this game like the plague.
