Use the arrow keys to move. The cursor will follow the mouse, but because I am bad at math it will get messed up when it goes near the top and right edges. You can destroy blocks, and there is infinite terrain. (Did I spell that right?) In any case, this is a very early version of this game. It took me a while to get the block ids working (they are read from a list using a ridiculous equation) Update - Sorry for the ugly cactus texture...the lame textures are because I was working more on loading the world well then making fancy textures.
I wanted to develop something like griffpatch's 2D Minecraft, but I made everything. The only thing I copied was using lists. - Update: I also used the cloning tiles idea.
