your dig is very badly implemented, why not just make 1 key to dig & it digs in whichever direction you are facing only as the dig infrequently doesn't work.
Some features couldn't be used if the player would dig in facing direction. For example you couldn't walk right and hold dig left to make serial digging fast in one direction. It is a vital feature on level 8, and in beginning of level 9 and other levels too.
Also if you would need to set always the facing of the player your response time would be slower.
In first level the picture shows how it is recommended to use the controls (WASD with K&L and arrows with Z&X)
awful. if you live long enough to select the 1st mission there's no explanation what you are supposed to do on that mission. there's also no instructins as to how to actually survive.
