So I was stuck in a level with 5 bats... And after quite a few attempts I figured it out. Yes I used only bats. And yes I broke the game :D
!Spoiler Aletrt!
So I thought, if bats can only pull player than what can I do to save myself? The answer was to wait until the playr comes to me and then throw all the bats behind his back. By that I forced the player to jump over me and he walked by :D I should get an achivement for this solution)))
