As with the previous few levels, the Runner is the only available character when first playing through the level. However, after unlocking other characters, any one of them can be used to play Level 4.
Level 4 includes more of the Crumbling tiles introduced in the previous level, as well as larger holes than before. The larger gaps are more likely to be a problem for new players, as they may require the jump button to be held down for a long time. The longer the jump button is held, the higher and farther the character will jump.
However, the gaps can be avoided and walked around if the player is observant.
Level 4 is not very difficult, though it may prove a challenge for some beginners. Watch out the large gaps, and the rest of the level will be easy.
Note that there is a glitch that when you use the Student to move all the way from Level 1 to Level 4 without moving sideways, she will fall through the Normal tile she is on.
This glitch was found by Random Pro.
This achievement is of intermediate difficulty, as it is likely to be hard for beginners to complete, but more experienced players will have an easier time attempting it.
Walk along the small paths in between the large gaps to avoid falling through. Move diagonally when necessary to avoid stepping on any Crumbling tiles. Remember that jumping, even just once, or dislodging any crumbling tiles, will prevent the achievement from being earned.
