If this is an elephant, how the hell can it jump so high?
Because it's a flash game.
How the hell can it jump at all?
Elephants can jump.
If this Troper remembers correctly, Rhinoceroses cannot jump.
According to this random internet page Elephants can't jump.
Elephants, rhinos, hippos, and sloths cannot jump, but this elephant is a lot lighter than usual.
In 2D platformers, everybody jumps a couple of times their height as a default.
In Achievement Unlocked 2, what are you supposed do when your keyboard simply doesn't have the buttons you're supposed to push? A missing tilde button is all that's between me and victory. Such an annoying oversight in an otherwise amusing game.
Just use the on-screen keyboard. That should have a tilde key.
I just ran a finger over every single key (on a non-QWERTY keyboard), that worked eventually.
