I just realized how troll this developer is. When mentioning about a possible bonus if you get the percentage really high, he says "If you do that, there *MIGHT* be a cool bonus!"
That means that there also MIGHT NOT

dont support this ShIt game

I lost my day playing it, but i loved! LRLLRLRR=last pattern, but I can't break through the last Door D:

This isn't even a game. It is a poor attempt at abusing your basic instincts of accomplishment. DO NOT WASTE YOUR TIME WITH THIS. You can get to 100% by simply hold left or right and clicking outside of the flash, causing your character to keep moving without your involvement, but that's if you feel like spending over an hour of your time with this piece of doo doo.

It is a bit boring in the beginning, but the more you play, the more you want to get to the end. Btw, the game says "Game Over" when it is done.

For the benefit of those who are stuck I decided to give hints on how to beat the game. Consider this a ###Spoiler-WARNING!###
The game won't auto-pause so you can start grinding by pressing left or right and then clicking outside of the window. The ninja should be running amok until you stop him.
As soon as the trophies are unlocked (IIRC at 500coins), it is a good idea to get them, since having all will speed up your grinding.
Trophies are awarded for doing certain tnings for a time:
-going left
-alternating between left and right
-going right
-standing still
-standing still in front of a candle
-pressing left and right simultaneously
-collecting a certain amount of coins
-collecting all the other trophies
Collecting all trophies gives you the first zenith. The other zeniths are:
-1048575 coins
-LVL 63
-2047 attempts
-32767 distance
-4095 time
-31 medals
This isn't all, though. To advance further, you have to find a sequence consisting of 8 times left or right (leaving the screen either right or left) I just played around to find it and don't remember the sequence so good luck finding the right one out of 256. The current sequence can be seen superimposed on the floor.
When you find the sequence you have to do a similar task in order to bust through a door to the right and you will get to see the real ending.

Don't try this "game", don't waste time, do not trust those who want you to play whis because of a deep message or a cool secret because there are none.
And because you need these stats to get to the ending:
Level 63
7 (plus the final one) Trophies
1048575 Coins
2047 Attempts
32767 Distance
4095 Time more than 1 hour.
31 Medals
How this made it to newgrounds is beyond me, not to mention getting the front page.
So 0 out of 5, don't waste your time.
