Downloading Lifeslide 1.3.1 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. This free Mac app was originally developed by Dreamteck Ltd. The program lies within Games, more precisely Arcade.
From the developer:
Lifeslide lets you take a flight as a paper plane as you embark on a metaphorical journey through seven stages of life. The braver you are, the better you will fly. You can dive down close to the ground to increase your speed and make split-second decisions as you traverse the ever-changing world around you. Each level has a unique twist and you will need to adapt in order to play the game of...life.
You may want to check out more Mac applications, such as TuxRacer, Balls Trial or Varmintz, which might be similar to Lifeslide.
