Scratch

Yep. It was quite easy to make. 

Anyways so here you go. My box pushing engine.

It has best performance online (depending on your computer). If there are any glitches, comment them on the project.

This engine was designed for Scratchers to use it in their own platformers. I may be using this in other projects of mine.

If you want, you can add some improvements.

Anyways, so click here to check it out!
