Eitr? I hardly even know her!
Eitr. Well, this looks lovely. Dungeons. Long pixel limbs. Flaming swords. Skeletons. Dashes. "Touch?" prompts. My kind of jam. And two people made this?
Also, the second half of the trailer is a bit more exciting and diverse, showing off cool special moves, bigger enemies, boss fights, fights with multiple enemies, and so on. Skip ahead a bit if the high hit count one on one stuff in the beginning doesn't get you going.
There's also some cool stuff at the development blog. Like this spooky scary skeleton-filled stress test.
