Very pleasant!
As a fan of the Mother series I really enjoy the clear inspiration derived from it and the character dialogue was enjoyable and funny.
Honestly even though the "echoes" theme was hardly worked in, it almost felt as if that was part of the comedic experience. Seeing "ECHO" always typed in all caps felt sarcastic in a way which I found humorous and was reminiscent of Earthbound's general sarcastic nature.
I enjoyed this one, probably one of my favorites of the one's I've played from the jam thus far.
