0 0 0Here is the path I used. It doesn't require advanced techniques, just a little practice. This time can be greatly improved.
0 0 0As it says, you need to complete the game(by getting to the yellow button) within 8 minutes. This should be very easy if you're at all into speedrunning, with people reportedly getting times below 3 minutes.Even if you're like me and not that much into speedrunning(or just rather bad at skill based games, also like me), this is still quite easy. I got this achievement on my first speedrun try, after getting the non speedrun achievements. Just keep going through the game - the fastest way to move through it will naturally become obvious as you play, and you'll have the achievement in no time!
