The variable in the top right is the 'Ghost' effect variable. It tells you the percentage of the ghost effect. The red potion, which is made of boxes, changes the 'Pixelate' effect. Fullscreen is recommended, so you can read the potion labels and other text! The pink box is your volume. to change your volume, click the volume button to the left of the box that says 'Page 1'. The volume has 4 Levels-100%, 75%, 50% and 25%. If you click it again when it is at 25%, it will go back to 100%.
Update! You can now use other sprites such as dogs! Oops, update isn't working. Just stick with Scratch. I was inspired by another game that was like this, except with 1 song repeatedly playing, no labels, no volume button, no visible variable, no music disk and no 2nd page. I forgot the name of the title and the person who made it, but thanks anyway! For the click sound effect, I used my own mouth. I also made something like the spinning music disk in 'The Tiny Town Game' (Try it!), that tells you what song is playing and used one myself! Everything else was created by me, except for the music, background and the ghost potion colours (some people make it rainbow(idk why)). I got the songs 'Bossa Me' and 'Winds of Fjords (Mimomus)' from 101 Soundboards.
