Okay, thank you for the quick resolution! :)

I feel like the instructions should be more clear. As it turns out, I kept failing the kata because I was accepting smiley faces that had trash letters/symbols at the end. It was never specified that this is a problem, and you wouldn't think it is, considering :-)k is still a smiley face per definition of the rules. I eventually found this out through trial and error, but I believe clearer instructions on this issue would help tremendously.

P.S. I still thought it was a good kata despite this issue
