Could someone fix this?

I've got a problem (bug) with directions
I want to make the RED bubbles go along the background blocks...
They don't need to turn when there's a turn formed with backgrounds

And please look and maybe fix it, PLEASE!!!!!!!!

I dont understand what it is you are wanting.
Could you explain in more detail pleace?

I'm guessing you want the bubbles to change direction when they hit a wall?

Probably, if there are two possible directions, pick one at random, yes?

What else do you want them to do? Tell us........
