This project is a platformer engine intended for creating own games with no programming skills. You just need to draw your own levels and place many fun elements supported by the engine, like stairs, teleporters, moving platforms, switchs, blocks, monsters, etc... This project is a tutorial build with the engine. Just 'play' the tutorial to discover all the engine features. If you want to start your game from scratch I recommend to start with "Retro platformer Engine Base" https://scratch.mit.edu/projects/382446797/ You have a playable example on https://scratch.mit.edu/projects/382772300/ Check related studio for more examples https://scratch.mit.edu/studios/26175426/
03/04/2020 This project took me a lot of time and I abandoned it for a long time. But this coronavirus stuff gave me a plenty of time to recover the thing and the idea to offer scratchers some fun source in no so fun times. Hope you keep healthy and build great stories and games.
