About three months ago someone posted a netflify app called "Treksit", which was flagged for plagiarization: https://news.ycombinator.com/item?id=24050651

Both "Treksit" and "Blocks" use the same ambient music and have the same attribution in the credits:

> Huge thanks to Mary Lou (Manoela Ilic) from Codrops for the constant inspiration.

These are almost certainly by the same person, under two different accounts. That doesn't automatically mean this was also plagiarized, but it's extremely suspicious.
