Introduction
This is level 4 of the I-Tunnel.

Gameplay
This level has multiple sideways conveyor tiles. The last two jumps are near impossible with all characters, and you need to barely tap the jump button for each. This is why I suggest using the Runner or the Student, because they can do short jumps. The Runner can easily manage the rest of the snake due to her great maneuverability. The Student is the same, except you can turn gravity upside-down when necessary.
You've done well to get this far! However, the next one is really hard and is arguably the hardest level in the game.
