Click to place a block! [A], [D]: Cycle left and right. [W], [S]: Rotate block [R]: Reset rotation, color, effects [Zero]: Clear all. [1-5]: Stamp example scene. Modes: When you're in a mode other than "Block", press that mode's key again to return to Block mode. [E]: Erase (Delete a tile) [T]: Outline/Tool (Add black outlines to the blocks. This is the main feature of this editor, since the outlines can shape the blocks visually). When in tool mode, press [F] to flip half slants and related outlines. Block modes: [C]: Color (shift color effect) [B]: Brightness (shift brightness effect) [G]: Ghost (shift transparency) In any of these modes, press the key again to return to block. When you're done editing, switch to block mode and press [Q]. This will hide the cursor and mode indicator, allowing you to right-click the stage and save the image you've made. Then, open it in an image editor and fill in the white areas with transparent.
Graphics are from Mario or made by me :) I made this thinking it could be used with my new platformer engine, so I might do that. Or you can :D
