You may go into the sprite1 sprite and backpack or copy the four codes. You may request a code for me to get you. I might say I can or just Nah. Click the background to test the code to see if you like it. You may slow or speed up the walk (well of course you can.) Down and left have negatives so when altering, remember to add the negative before the number.
Thx for cooltext.com for that cool text! The rest of the coding and designing is me! Thx for google for the thumbnail background
