Ok, so with help of Google Translate I could understand the Korean, I figured out that you have to transform your weapon to be able to kill the shield guys. But how do you kill the last guy? With the black health bar? And also, I depleted my blue energy, how can you recharge? I'm now stuck.
First of all, Thanks for your playing!! And sorry my late Reply.
Answers the questions
1. how do you kill the last guy? With the black health bar?
=> I can't figure out your saying, maybe I assume that guy is Boss. If that guy is Boss you can kill him by Attack key as you did kill other enemys.
When I play the game after your comment, but I couldn't find 'the black health bar'. Sorry for my bad answer.
are you saying this guy?
