I think Hoppi needs a small change regarding her difficulty. She’s one of the obstacles that consumes the most energy, since you have to close the door and flash the light at her face several times. The mechanic itself is simple, but you still have to perform two steps to deal with her.
However, nerfing Hoppi wouldn’t be my suggestion. Instead, I think there should be some kind of sound or noise to indicate when she has reached the door. Her footsteps seem to be extremely quiet, and right now, the only way I can tell she’s there is by flashing the light. Other than that, there’s no other indication that helps me notice her presence.
I think adding a simple sound cue when she reaches the door would make the mechanic feel more fair without necessarily reducing the obstacle’s difficulty.
