Only took me about 12 minutes to beat, but with 53 deaths along the way. That was really fun. It's truly the Dark Souls of one-button platformers... It's got all the key challenging dark fantasy action game elements: respawning to compensate for the unforgiving danger, tricky timing in the swordfights, traps that seem unfair the first time, no pausing, and skeletons. I'd also really like to see this concept expanded into a full game.
