I like the Idea of fencing your way through skeletons. I found the blue skeletons impossible to pass and I thought I could use the charge move to get passed them but I only glowed pink and nothing happened (and I died. *RIP*).
You need to attack (release X) when the enemy starts attacking. If you attack before that, it does not work. True, you can only kill blue skeletons with charge attacks. Thank you for playing & writing a comment! :)
