Hitting the bushes or the logs doesn't appear to slow you down, and if you're always jumping then the killer will always move further away from you instead of closer. When the bush or log hits the killer, it also resets his position making the game hard to understand. Could perhaps improve a bit though with some sound effects and intense music to really show the intensity of the game 

Would benefit if you could die ass it seems that the death is bug or not finished. also would be good if the enemy could caught you if you hit the log or something like that
