Hey, thanks for the feedback!
Funny enough, we were actually having a silent protagonist for the majority of development until we became aware of some communicative issues. Mainly telling players that they are on the right path and telling players that they've found something important. Utilizing dialogue cues for those scenarios was the most convenient solution especially because time was very scarce. So giving up on a silent protagonist was a casualty we did to address some other issues. However, there are arguably better solutions for those problems.
But anyway I am glad that you've pointed it out. Appreciate it!
