This was a beautiful experience, unfinished though it may be. The art is gorgeous, and whether intentional or not, I find the sketchiness of the lines very appealing. The characters are very expressive and I get a clear idea of what is being conveyed without dialogue.
Correct me if I'm wrong-- as I'm a big fan of mythology, but I'm rather lacking with Norse myth --the soldier in question went to Helhiem instead of the warrior's Valhalla, because he did not meet the criteria for entry. He is satisfied with this outcome because his wife is also in Helhiem, and he would rather not be separated from her, much to the Valkyrie's dismay, who had wandered far to retrieve him, as she believes he deserves a place in Valhalla instead?
If I'm correct in my assumption, then I think this was a truly beautiful approach to the theme. Not only does the Valkyrie fly, but she was attempting to make a soul "fly" to higher planes despite them not wanting to. The actual mechanics of the game were, as others said, somewhat lacking, but overall I think this had a lot of promise and was very pleasant as is.
I am a little saddened to see you won't be continuing work on it, but that's very understandable. I would love to see what else you guys make in the future.
