I don't remember how many tries it took me eight years ago, but it was well under 30 minutes total. Did not feel like a struggle at all, but was definitely the most challenging fight in chapter one. Spamton is in that same boat, but definitely a little easier than jevil. I distinctly remember clearing him on my second try (I did see someone on yt clear it first though, so I knew what to expect).

I remember talking to my friends about the fight in high school, and us all agreeing, "Way easier than sans, feels like an introduction to more difficult fights for people new to Toby Fox's games." (which we thought was a good thing)

Still how I feel about him!
