Sand Land

To play:

A & D to move left and right.

Space to jump.

hold W to make you jump higher and fall slower

hold S to make you fall faster and jump lower. 

If you hit a cactus that isn't glowing,  a tumbleweed, or a robot tumbleweed then you die.

Cactus:

They go along the sand, if you hit one you die. There is a glowing variation that if you get it it makes your W power stronger, can even make you fly if you get enough of them. (There is a easter egg that may perhaps spawn in powerups.... :P)

Clouds:

If you touch one, it will bounce you up unless you are holding S, in which case you will go right through the cloud down.

Tumbleweed:

It bounces on the sand and the top of the map. As the game goes on it gets more drastic in it's bounces.

Robot Tumbleweed:

Always bounces to the level that your character is on.
