I would say that at its state it definitely appeals to those looking for a challenge: the moment I died, I immediately told myself "alright, I gotta do this"
But it's also easy to get the gist of it, and while it can be challenging, it's also fun to just jump around :)
I added some comments about the game to the description. Maybe it can help you to look at game difficulty with new eyes ) If you have time for that, of course!
