Hey! Thanks so much for commenting. I just now saw it and don’t remember getting a notification so my apologies for the late response.
All of the art is public domain with the exception of a couple pieces by William McAusland, and you’re absolutely right. There should be a credits page?
Also you’re right about this being an alpha. RedHack was the working title.
I’m pulling the game until I can make these updates. Let me know please if you have any further questions or concerns.
