Looks ike regular substitution but with a one to many mapping schema.
If this is true, then so is the following:
First, it is indeed a one-time pad methodology.
Second, the message is not large enough notice statistics.
My guess is that this is a normal substitution ring, but it must roll or simply defy a stastically typical English sentence.
I have one rolling ring that comes up with this.....
K#> = H
*.+ = E
}'+ = L
++5 = L
K"> = O
+!p = W
2!* = O
,+S = R
,>S = L
3>\ = D
-f = .
