Use WASD to move, click and hold to break blocks within a two-block vicinity of you. Go to the right edge to enter a new area. Press SPACE or B to toggle Build Mode. Click when in build mode to place a block. Press R to reset. Try not to fall.
Thanks to Griffpatch for the platformer tutorial for the.. y'know, platformer aspect of this. Also thanks to his Paper Minecraft for inspiration. Thanks to Mojang for the original Minecraft.
