EchoingDeaths is licensed under the Apache License 2.0 with one extra condition, the Commons Clause. Here is what that means for you, in plain words.
The Apache 2.0 license is broad. You can take EchoingDeaths and use it, for any purpose, at no cost:
The Commons Clause adds a single restriction to the above:
Everything the clause does not explicitly restrict remains fully allowed under Apache 2.0.
If you redistribute EchoingDeaths (whole or as a modified build), keep the license notices intact: your copy must carry the Apache 2.0 license text and the Commons Clause notice, including the restriction above. That is the only attribution the license asks for.
This page is a friendly summary, not the license. The authoritative text is the LICENSE file in the repository. If anything here and the LICENSE file disagree, the LICENSE file wins.
