complete! sadly the devastation caused by version 2 of this canon is significantly less than its original form, but it can be fired repeatedly without having to rebuild the whole thing :D now features 2 firing modes: the original canyon maker, and a new angled shot that results in a vertical shaft. should be noted that i'm using a very basic "cannon" to throw the tnt, upgrading should cause canyon to be dug at a distance from the device, or perhaps even give the ability to dig horizontal tunnels, though ive not (yet) tested either possibility.
