Just FYI, this is probably the least useful save code engine you'll ever come across, which is okay, because this isn't an engine. I will be using this in my Pen Platformer Maker, which (if things go well), will be out soon. Also, press space to get the savecode. Press space again to decode it.
All by me. The more I think about this, the more I think this isn't a save code thingy. The one thing this can be used for is the "Decode" block, which just separates the string "savecode" by spaces. :)
