Been working on top down procedurally generated destructible terrain. The terrain will re-tile itself correctly every time there is an explosion.

You can try the HTML5 Demo
Controls are:
Press “R†to generate a new level
Hold “Z†to zoom
Arrow Keys scroll level while zoomed
Right Click to place an explosion and blow stuff up
First draft so I can make some improvements. Badly pixelled tiles are inspired by a tileset from "Nuclear Throne"
