Instructions- 6 key for enemys. 5 key for special block types. You headbump the brick block to break it. Down to crouch (not on semi-solids). In editor c key to switch character. The life thing switches the character in the play mode (the life moves). Can place goombas inside mystery blocks. Two types of goombas which start in direction specified (noted by their foot). Goombas can also place on horizontal pipe (edges only) (the goombas have to point in the same direction as the opening). Only 6 goombas come out of a pipe. This does not work for horizontal pipes. If a mystery block under a life is punched the life bounces and changes direction. Grey crosses are enemy boundaries (not life). Only visible in editor. They can be placed on other tiles and are selected by 6 key. Music symbol block is a trampoline (same concept in sma4). The mario posing with the peace symbol is the spawn point. Z is jump and x is crouch. You cannot move if you are in crouch position. Those are all the mods I remember. Rest instructions and code is just like @griffpatch 's tile scrolling platformer.
