Great! Thank you! :)

CodeWars seems to have made some changes. I revised the kata and it should work for you now.

I found the key and i set the variable... but it does not let me through. Something is wrong here.

I have the same problem

I think that there is some error in service work, because even I try to submit only one line

Bomb.Explode();

I just have

Passed: 0 Failed: 0

and the log message

 The wire was "cut":

but i never can get the message like "BOOM! ... ".

I think that the code is failing somewere inside of testing methods.
