There is no guide to complete this game. You just need to get used to it, a little patience and everything will work out for you.
My tactic is to act out of the situation. Shoot off opponents immediately when they appear on the left, constantly moving. If you are bullied, move in the opposite direction or into a plus or minus safe zone.
I looked at the English-language guide, where you just have to stand still and move the mouse to get through, but I don't know, I tried - the result is sad)
I recorded a video of the passage with a large margin especially for you. Almost 200 seconds

Recommendations: do not set the mouse sensitivity too low, but you should not set it too high either, since it is important to accurately hit the enemy. Personally, I used 1200 DPI, adjust to yourself personally, because we are all different. I also had chewing gum on hand, and to be more calm, I ate it while playing) And I also advise you not to keep track of time, because when you see that you have just a little bit left, you will most likely relax and lose concentration, thereby losing lives and losing before reaching 150 seconds. I personally died once at 149.58 seconds, don't repeat my mistakes):
And so, if you follow these tactics and recommendations, then this game will not cause you any big problems. Good luck) Please support me if my guide has helped you)
