Get the following error when deploying: ParserError: Expected primary expression

[nidhhoggr]

Is this repository still maintained? It's still referenced in the OpenSea documentation. When following the README line-by-line the following error will be reproduced because there seems to be a placeholder in the Creature.sol smart contract.

Command ran:

yarn  truffle deploy --network rinkeby

Resulting Error Output:

✔ Fetching solc version list from solc-bin. Attempt #1

ParserError: Expected primary expression.

Compilation failed. See above.

error Command failed with exit code 1.

Shouldn't there be some explanation to replacing this before running truffle deploy?
