Thanks, the details section doesn't specify if for a given movement type (e.g. diagonal) all directions are allowed or if these should be restricted to the sample ones (in the image and description). IMO while the answer might be obvious (for an Android phone lock screen) clearly pointing this out in the manual among the possible movements description might be useful.

Hello, are the following paths acceptable ?
A -> H
C -> H
C -> I
I -> B
