It's pretty fun. Kind of takes the dignity out of that funerary ritual (I'm aware it's not real, but the idea has dignity). I like how Odin cares more about the ships than the souls.
I think this game does need tutorials, but there's a lot of room for improvement. The ones you have are slow, non-interactive, over-explain some things and under-explain others. Most of the things in the tutorial could have been explained in-game, with a "shoot here" crosshair the first time you encounter a specific monster. I had no idea what to do when it was raining until I saw your explanation in response to another review.
I don't think you're getting complaints because people don't want things explained at all, but because your tutorials are tedious and completely break the pace of the game.
