Ah yes! I read that before playing but only now I understand it. Cleaver, i like it!
I know how it feels having the idea but not having time. Another thing that I would had find really usefull is the possibility to view the movement capabilities of each elements at each level would have been very useful too.
P.S. This game reminded me a lot Onitama, if you haven't play it yet you should totally give it a try
