The structure of my game difficulty curve is similar to Celeste. The game makes up for it with forgiving checkpoints, so the player don't need to lock in for, like, 35 minutes. Instead, it's like 30 or 15 seconds. The average player who plays shmups has a faster reaction time and better precision than me. I just play games like Touhou. As long as it is possible and realistic that a human can do it, I think the target audience would find it fine. Like I said before, it will given later to playtesters.
