The platforming segment was kind of meant to encourage the player to go a different way, it feels hilariously rough because gravity is constantly swinging in that room, that's not just a visual effect! There is an inkheart at the end, so I hope that makes up for it. That section like most is completely skippable though. Instead of straight corridors, the rooms in my game go in loop de loops. Out of 16 rooms (not counting houses) you can complete the game only visiting 7 and fighting 2 out of 4 bosses.
