A standout premise exploring actual history. Hand-drawn art very wonderful, but in dire need of music to complete the atmosphere. Without it, and also without a declared end goal and sense of scope, the text and story are tough to get through.
Could use a proofreading pass "recording the experiences fomer slaves," "formerely," "either type of press words," "the WPA has commission you," "unfourtunately," "Issac," "refridgerated crap," "Hindoos," etc. Good practice to write scripts in Microsoft Word, Notepad, or another program that has autocorrect and porting it over, instead of writing directly in Godot or a JSON file.
Scene / environment transitions great, and the narrative system is well-implemented. The vocabulary inventory and interview mechanics are cool concepts also. The tabs on the vocabulary inventory UI box could use some padding. Most of the responses to the five "Ws" end up being redundant / irrelevant, so this would be all-the-more reason to cater the narrative via traditional multiple choice dialogue responses instead of the string input box.
I didn't really know how to progress after interviewing Harriet, Ishmael, and Isaac, so my playthrough ended there.
All-in-all, I love the authenticity and exploration of this premise. It's rare to find a game that cuts to the bone of the real injustices of history that are otherwise quick to get buried. Great courage and ambition.
