which way?

I really wanted to love this level. I was so excited by the premise of having to match up an entrance with an exit to get the right combination. I was also delighted that there was no sadistic electrocution of B inside the barn. Alas, I found that no matter which entrance I chose, one particular exit always succeeded in completion of the level.

The artwork of the barn (row houses, rail yard, ...) is great, as is the premise of the level. Thanks!
