sometimes i even have people make fun of me for what i do on scratch, they make me feel bad for making it or criticize it or the concept, no matter how proud of it i am or how long it took to make i always have someone say they don't like it or it could be better, it's so annoying that some people have to criticize everything somebody posts on here, maybe they thought that idea was funny, or cool, or maybe they just genuinely thought it was a good idea and they are proud of it, all i wanna say is don't listen to people who say your project is bad or dumb they only say that because they know they can't make something as good and wanna make themselves feel better by putting others down, basically do what you love, take pride in your work, and most of all i can't stress this enough have fun! ;p
remix this if you deal with a similar problem, read the instructions for more stuff that i couldn't add to the main project cuz i ran outta room
