It's your game, you know how everything works and i bet you have some experience playing these retro sidescrollers. But try to see it from a new player's perspective. The difficulty itself isn't even the problem, the problem is to have it this early in the game. I bet most of them havent gotten used to the controls yet. Your video tries to be a gotcha but even there, u the dev is struggling. You even reset the stage because you didnt have a good start lol.
People want easy stuffs on this days
I enjoy difficult games, but this is some ds2 level of bullshit.
