StarScapes

Oh that sounds interesting! Good luck with your game.

Hello forthebundle,

I messed with the code and it works the way DF said!

Thanks DF for your hard work and creative talents.

If you want I can send it to you vial email if you want.

Here is the changed script, just copy and paste into notepad, save as 'sketch.js' and write over a copy of the sketch.js file in the directory. Then just run the index.html file like normal:
