I play the game a little differently from most people.
Instead of escaping the creeper as quickly as possible, I build forces and drive back the creeper to its emitters.
Then, I bask on the glory of being able to stop indefinitely a relentless enemy, and finally escape.
Most times, I can manage to do it in less than 30 minutes time in-game, always in less than 40 minutes.
Can you do the same in less than 20 minutes? Less than 10 minutes?
Error when loading:
"The browser could not allocate enough memory for the WebGL content. If you are the developer of this content, try allocating less memory to your WebGL build in the WebGL player settings."

This is now fixed in version 3.0!
