This design will kill players without FPS capped at 30. The three-way junction tries to pull players backwards when exiting, fighting the existing inertia, losing, but reapplying another 'stack' of speed each grab attempt.

With higher FPS caps, this process has more time to render and continue, rapidly increasing inertia as it slams you against the exit side of the entrance pipe until you die.

Removing the hypertube entrance and wall support from the upper segment is sufficient for 60 fps players to exit properly, but at a 120 fps cap, I remained trapped, building up speed infinitely - depending on whether the devs accounted for this kind of loop, it could possibly crash the game.
