Move over Mario Maker , it’s time for a new Mario level creator. Screentendo is a brand new app made by Aaron Randall that allows you to create Mario levels using whatever is on your screen.
The app functions very simply. You can use it to drag and drop an area of your desktop to be Mario -ified. The app then uses whatever is on your screen to draw a bunch of Mario blocks for Mario to jump around on.
The app is just a proof of concept now and doesn’t have things like power ups or enemies, but given time this could be an interesting way to waste a few hours with custom Mario levels.
