What do you mean I can't have 2x big bertha?
The cannon moves in a funny way. It's quite an enjoyable mix, mining gets quite repetitive though. The fools gold is very annoying, because the detector gives just a slight glow and instead of mining I need to keep staring at the screen and wonder if it's safe to mine or not.
It's also quite annoying when I hit the lowest asteroid just after launching and there's no way to avoid this.
