Doshol up to chapter 2 of the problem ... (Hotline Miami)

hello to all fans of this game! I had such a problem! I have reached the 2nd chapter of the game and I can't go to the 2nd level! Well, there I seem to go to the arrow, it seems to translate, but it leaves me at the same level and I keep walking in the square and that's it!
It's a pity that way! The game is very good! help if anyone knows what!
