This is level 18 of the Low Power Tunnel.
In this level, you have to jump across the rectangular platforms. The gaps are large, so you need to use the high jumps. It is also harder to change gravity in midair, since the number of sides are only five, and there are large gaps, unless you use the Lizard.
Jump high and look for landing space. If you can do this, you will be able to pass this level.
Since in this level, although the tiles are dim in colour, the music doesn't stop and that the colours of the tiles doesn't change, we can deduce that they are all normal tiles instead of power tiles.
