This level is not too difficult. There are some indefinite numbers of crumbling tiles, yet they are mostly not connected to each other. If you step on one of them, not every tile will crumble. However, each side is only two-tiles-wide, so you won't have much space to let your character to avoid the holes and crumbling tiles. Yet, if you can successfully avoid the gaps and holes easily, you can surely finish this level with ease.
Sometimes, crumbling tiles come in patches. Going around to avoid them is not plausible for every turn. You can sometimes walk diagonally across these tiles to escape from crumbling these stuff. As for the holes, try to jump or turn. Don't decide at the last second, since some of the beginners still panic when they see a hole at this point, so think ahead of what is going to happen.
There are only six sides in this level, which is not a lot, though it has sides more than some levels, such as Level 1. yet still, it only has six sides so that changing gravity can be very apparently be seen. So, you will have to make yourself comfortable in this special gameplay mechanic.
Yet beware, there is a gap between the level and the next level. Don't drop your attention when you think you are about to beat this level. If you fail, you will have to play Level 7 again, which maybe a challenge to new players in this game.
