Art is top tier, 5 stars. Scenes are very well illustrated.
From a writing / story perspective, Elfheim is incredibly lacking.
There is one choice in this game, and it's the name of the MC. Because the MC is a Dragon Quest style slime with no agency, the game's characters have to carry you from set piece to set piece. Having a character that is weak, viscous and easily managed is convenient for CGs, but for a game? It's hard to fantasize or imagine yourself in the MC's shoes. You end up looking from the outside in, a voyeur of this useless slime, and it really detracts from the experience of these excellent illustrations.
I'd love to see real choices. Agency. If I'm basically a video game mob, where are my evil choices? My good choices? Maybe I want to transform into something that isn't a milquetoast little man? Give me some role playing. With a little more intention, Elfheim could really be something special.
All in all, 3/5 - average. The art really is that good, and I will be watching this game closely.
