Look at my profile for some easier levels.
Actually, this is easier than level 5-9, I think. No brain required
P.S: If you ever fall on level 10, just hold the left arrow.
Just to add, you can sword climb by jumping and slashing with the sword. Just like in the game GunZ, except that it is Jump>Slash>Jump>Dash>Slash>Jump>Dash>Slash. But don't do it. It's pointless and for noobs.
