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! 😄
Oh I almost forget! Sometimes when I restart the camera goes trought the floor (web version - fullscreen)
