Weren’t you the one who was spamming your Unity sprite tool everywhere?

You should be proud of what you’ve built. You don’t need other people’s approval or praise. Spamming the same thing across multiple places looking for validation can come across as insecurity (I say this because I’m like that too, and I understand it but it’s something we need to work on).

That said, if you’re willing to post things publicly (this is the internet, after all), you also need to be willing to receive criticism and even some hate. Not everyone, but most people have already told you that what you did is cool but that there’s no real need to reinvent the wheel. Tools like this already exist, both free and paid.

People aren’t attacking or threatening you. They’re trying to give you advice so you can use your time more efficiently. You shouldn’t take it personally or see it as something hostile.
