How to Play?

Best Free Green Gray World Game. Green Gray World can be very addictive to played. The graphic is simple, but the game is not so simple. My adrenaline pumped while playing this game. This is not just about action and adventure game, but also strategy. Can you complete all levels? Purpose of the game: The main goal pretty simple. You just need to move the player through all obstacles and enemies to the exit. At early levels, I'm sure you won't get any trouble at all to complete it. Don't expected the game going to be easy all the time, but in the contrary, it getting more difficult to complete if you are not very careful with your step. How to play: The main control is your keyboard. You can choose using left/right arrow keys or 'A'/'D' to move forward or backward. To jump, use 'W', 'key Up' or 'SPACEBAR'. You only have one life, so used it wise. If you step on the spike or bumped the the enemies, game over. You can kill enemies by jumping on them. Use helpful objects, while avoiding deadly ones, to make it to the exit of each level. Special trick: My advice to you, avoid and run. That's the rule. Watch your step since you can easily slipped off and fall in to the deadly ones. It is not too hard to complete when you have get used.
