If your having trouble defeating the 1st boss then here is what you should do:
<span class="wikilists">
- Once the battle starts, go upstairs (if you cant find the stairs then just look around and then you should see some stairs)</li>
- Go up the stairs</li>
- boss will eventually shoot blue things (lasers?) at you, just doge them and throw shruikens and his face (probably 5-10+)</li>
- will fall down and then a green hexagon/emerald will appear on his body, just hit it and he will eventually die.</li>
</span><!-- wikilists -->
---TIPS---
If your low on health then there will be some health pick ups you can use, they will be on the 2nd floor
Dont go near the boss when you are fighting since he will unlease a swipe which take your health away.
