Welcome to the forum. I won without doing anything.... One of the B bots just walk to the win - you'll need some more game play in your level. Not sure why this is in the exploit section aside from all the Bs?
@Meko Guy who are you man? How do you find interesting ways to win a level. Why I didn't thought that? Just open the level. And wait.... .... .... ! Hurray! You won!
@Meko Guy so I must say, you first go through the level only by watching. Where as I search the Win and analise backward path.
@Pratik Bhalerao - In fact - no. I won with B first and when I came here to comment, the 2nd win occurred while I was typing, so replayed without doing nothing - same happened so I changed my comment.
