Do you have what it takes? Try to get the highest score you can in Birdy, a game where you jump over cacti. Its easier said than done. How does it work?
Tap on your screen to make Birdy jump, tap again and he will double jump. Sounds easy right? You still need to get over those cacti though. Try timing your jumps, Birdy doesn't have a round body, so the direction Birdy is heading really depends on your timing.
