Precisely the game is made so that it is not easy to succeed.
There was a person who succeeded in the game and made a youtube video :
Thanks to you for playing my game. Sorry for the bug where you cross the wall but I don't know how to fix it.
You are incredible normally I predicted that we could not go until the 13th round if we had the skill but you went further (recovering grenades with the packs was not planned but is consistent) and more in only 5 part
My second comment in 2.5 years makes me extremely happy, its shows me that my efforts are not totally useless
Good luck to you for the future
Hello, the game is over but almost impossible but everything works I checked part by part, Your problem comes from which part of the game?
If you are on the part with star and red arrow for the first time here you will jump infinitely in this part
Otherwise the part after that (after the shurikens and the fire at the same time) you have to find a secret passage (clue: in the ceiling)
Also you have to jump continuously on the rope to reach the top (you need continuous contact with the rope or you can't)
Translate with google If you want I can set up a backup
Thanks for my first comment feel free to watch my other games
if it is none of the cases put another comment
