Player: WASD/Arrow Keys to move. Level Editor: 0 to turn on. Blocks you will place turn slightly faded. Click to place. E over existing block to turn into that block(E over grass switches what you will place to grass). Space will use relative positioning to help draw large buildings. 1,2, or 3 will change which layer you are editing on so that you can place multiple tiles in one square. Tiles on layer 3 will be able to have the player go behind them and not appear visible. Click the same number that your layer is, (layer 1 press 1 again) and you will enter onion skin mode. This is where everything that is not in your layer will be faded out. Press P to turn on collision points. Press 1 while over a white dot to make it a collision point where the player is stopped-X to delete. Blue when it is a collision point, faded white when not. Tip: if you can not switch layers, check if collision point is on in the editor. If it is, turn it off. If you can go through tiles that you don't want to be non-existent(in the collision world) check if it is on layers 1 or 2, and check if it has collision pins in the right place.
