Hey there! Most people aren't able to immediately play Scratch 2 project files, so I've ported the game to SWF and EXE to assist other people.
For porting SB2 to SWF I used https://junebeetle.github.io/converter/.
For porting SWF to EXE I used http://swftools.sourceforge.net/swf-to-exe.html.

If you're skeptical of my builds, you can build it yourself using the tools I linked.
