Niffelheim looks cool at first! It's this viking survival game with a neat hand-drawn art style. But man, it gets repetitive and grindy pretty fast. Combat feels clunky, and it's way too easy to die from like, a single poison spider. There's a story, but it's super basic. It's a decent time-waster if you're really into Norse stuff and don't mind endless resource gathering, but overall, it left me feeling kinda cold.
