Important: If it glitches, just restart. Click C to start. Press S for a square, W for a star, D for a diamond, T for a triangle, A for the word "wow", B for a balloon, Q for a square+heart, Z for a smiley face, F for a snowflake, R for a random mouse trail, and Up arrow to clear all trails. Use numbers for raining trails. Click space to change background! If you press P you get a special trail (but make sure you have trails on first)! PS: random will NOT give you the special trail!
I used the Mouse Trail Tutorials by Orange_Lion. You can see it here: https://scratch.mit.edu/projects/327907705/ Comment ideas for mouse trails! =D
