To be fairly honest, I did notice that the aiming is a bit of an issue, but in my mind there was basically no way to fix it due to the way the game is programmed. I'll try adding some aim assist or some remedy to this in the future, but I can't really make any promises. The earth's health on the other hand is just a thing of preference, I made it that you need 20 hits to the earth, since I didn't wanna make it too difficult. Thank you for the feedback!
