It’s a little tricky since the text isn’t a sprite. What I did was create a variable at the beginning called “textVisible” I set it equal to 1. Then, in the same place where the heart gets changed to a corgi, I set the textVisible to 0. Then in the block of code where you print the text, I just put that into a conditional block so the text will only display when “textVisible” ==1.
You could do something similar with the Happy Valentine’s Day text as well, so the space bar going down would change a variable from false (0) to be true (1) and the text would constantly display when the variable was true.
Give it a shot and if you can’t get it to work, we can try to assist further!
