Update log:
9/01/16 - Sorry guys, but I decided to stop updating this. Scratch is simply to slow for my liquid engine, so I decided to port this project to javascript. Additionally, there's a very annoying bug in the project, and removing it would problably cost more time than making a new generator.
8/30/16 - I made lava getting added at world generation, but that lagged too much so I didn't upload it yet. You can view it at http://phosphorus.github.io/app.html?id=118959267&turbo=false&full-screen=true&nothing=scratch.mit.edu
8/30/16 - fixed a small light bug ☆ added water, but the engine doesn't really work, so the are a lot of liquid bugs ☆ added also lava, but it doesn't get add at world generation
8/28/16 - fixed (hopefully) all movement bugs ☆ press [P] to generate a picture with high-quality shadow
8/27/16 - shadow
8/26/16 - trees now get destroyed if the block under them gets mined ☆ you can only mine within a range of 6 blocks
8/24/16 - click to destroy blocks, only grass, dirt and stone can be destroyed
