If you are having difficulty scoring 40,000 points in a single playthrough to obtain the “get a life..” achievement, I recommend you do what I did.

what I did: If you've played a little, you already know that there are some pink portals spread across the map and that if you enter them they will give you 1000 points and send you to a new map. Just enter these pink portals 40 times, it seems crazy but it's fast. I entered 40 times and got around 40 thousand points!

TIP: IF YOU DON'T FIND A PINK PORTAL JUST GO TO THE BELOW OF THE MAP, IN THE COMPLETELY WHITE PART BELOW... THE GAME WILL LAUNCH YOU TO ANOTHER MAP AND YOU MUST LOOK FOR MORE PORTALS, REPEAT THIS SEVERAL TIMES!
