The hammer animation is very nice. This was definitely a fun game. There is some strange sound at some points very high pitched - my ears didn't enjoy that. Other than that very nice game :)
Yeah, I reckon it's opening sound, set at looping unintentionally. I added sounds at last moment, and only tested with checking in my mind whether things that should play are playing or not, and forgot to notice things that shouldn't be playing are taken care of or not.
