It's an interesting concept and the controls are solid.  There is a lot of risk/reward involved when you have to stop and dig and I feel that requires a little bit of balancing  (Maybe the digging shoud be a little bit faster or  perhaps increasinf the  walking speed of the playable characters...)

¡Great job! I hope you keep working on it!  😄
