arrow keys or wasd to move 0 to switch to editor mode when there use 1 to be able to choose ground tiles, 2 for other solid blocks, 3 for the semisolid platform, 4 for the spawnpoint and coins and 9 to select goombas or mushrooms press e to chose whatever your mouse is on press l to pick a level and potentially save(saving only works once the project has been remixed) press r to reset a level(only way to change max size currently) spacebar along with 0 is the only way to properly save changes as unlike other version of this tutorial I opted to not have it save default
Just a basic version of the tile scrolling stuff following Griffpatch's code however I do plan on making something larger with a copy of this later two changes I did make to this however is the abilities to place a set of coins infront of a semi solid platform and to place any thing selected with the 9 key inside ?blocks
