Thoughts:
Some strong visual storytelling from the get-go, rough graphics with cool perspectives, reminds me a bit of one-punch man.
There are spelling errors almost immediately, shit like that is hard to spot on your own, I have trouble with it as well. Send the script to someone and have them look over it.
While the music is not yours I think you have made some good choices.
The character designs are strong and appealing. I am very much a sucker for some silly names in a serious narrative.
Story seems interesting even in these early stages. Jagr has a cute hat.
The Werner Herzog documentary is actually really fucking good, I will assume you have actually seen it. Roman references, noice, if you like shit like that I would recommend you getting into the old greeks as well, Ovidius in particular, is a favorite of mine. There are collections of his works, the “metamorphosis” one is great. I choose to trust Jagr…
Suggestions:
I am very much biased but I would run with this story and art style and go full rpg-maker with visual novel cutscenes in between exploration and puzzle solving if I was you.
