Sketch Nation is a wonderful free app (iOS/Android) and website for creating games. Sketch Nation reminds me of Pixel Press Floors but w/out the paper. All a student has to do is select their category of game (i.e. platform, jumping, etc) then draw their backgrounds/characters/items and let Sketch Nation do the rest. The advanced level editor will help students create more complex games and work on their STEM skills. Sketch Nation even has a nice section for education w/ a collection of games created by students.
I highly recommend checking out Sketch Nation by clicking here!!!
