This is the second level in the H-Tunnel.
Use the Jack-o-Lantern if you have finished the Low-power Tunnel(which would be a very good idea). This will help you to turn more quickly and make the jumps. The Skater cannot turn quickly, and the Runner doesn't jump too far. With the Jack-o-Lantern you should pass this easily.
If you don't have the costume, you can still buy it in the shop. But if you don't have enough power cells, you can still beat this level by using long jumps with the Runner/Skater while running on the conveyor tiles. Since they all point forward, you can get enough momentum to pass those gaps and reach the other platforms. But be careful, since there are many directional tiles, so don't run too fast or you may jump over and miss the next platform.
Using the Skater is not recommended since his maneuverability is too low and with the increased speed of the Conveyor Tiles, it is very likely to let the Skater not turning round quick enough and end up tumbling into space.
The Student would even be boosted by the fast conveyors, making her less painfully slow, and you can jump/flip across large gaps with ease, and you should pass this level without too much trouble.
