Hm what i would suggest is some notice of what your doing. I've had mining going on for a while now and just noticed that the color of the mineral has changed as the pick has as well but I'm afraid I'm not a huge runescape player to know exactly what i'm mining or what my pick is now made of. So some notice would be nice.
WASD shifts you slightly when you are in the air, to help you to hit things to bounce off of.
The things that hurt you are spikes. Spikes hang in the air on balloons, UFO's will stop you as well.
Guns you use to shoot the turtle to avoid spikes on the ground by keeping him in the air longer.
