Ha! I love that we both used such similar time periods and locations! (My submission was primarily for HalloweenJam, but I tried to make the Viking longhouses and ring fort as realistic as possible.)
I had mostly focused on Viking mythology and architecture. I was aiming to have it set around 1100AD, during the Christianisation of Scandinavia, but unfortunately I didn't have time to weave those themes into the game.
Also, well done on your submission :). I left more feedback on the submission page, but I really enjoyed it!
