Diep just sent a DMCA Takedown Notice to Havre.io

This morning, I recieved a dmca takedown notice from 3am experiences' lawyers regarding my game havre.io. They seem to be under the impression they can take down any game inspired by theirs. Havre.io does not contain any material copyrighted by them. All the code is owned and written by me only. I will not take down Havre.io and will keep working on it, and keep listening to what the community has been asking for.
