| This level is hard!
This level is rather difficult. It can challenge veteran players and most beginners cannot finish this level. Most players consider it to be a hard level. Even elite players may have trouble beating this in one attempt. Good luck in beating this level!
This is the first level of the H-tunnel, which is also formerly called the Probably the Way Onwards tunnel.
Before you finish this level, it is called Probably the Way Onwards, part 1, but after finishing it, its name is changed to Level H-1.
Apart from the levels from N-tunnel and I-tunnel, it seems that the levels from this H-tunnel has the directional tiles in it too.
Like playing the levels with directional tiles, you need great maneuverability to pass the level. Try to do gravity changing in midair. This helps getting you in midair for as long time as possible. The directional tiles in this level all point forward, so it's best to run on them, and do a big, long jump.
