You can create platformer levels by selecting a block in the editor under the icon with a square in it, and place it were you want using the S key to place, you can also move in the editor by pressing the D key, and you will go wherever you point your mouse. You use the turn icon to turn blocks by pressing the turn icon, and use the A key to delete a block when you mouse is above it. Click the I button to get the information of the block your holding, and press the "pause and play" button the play your level. You walk around by holding your mouse down, and the player will go in the direction of you mouse, and the farther away your mouse is from the player, the faster you player goes.
The "Wrecking blocks" the move around are kind of buggy, also moving fast enough can dislocate the blocks, but only by a block at most. and bullets don't really move with the blocks.
