Oh, the second boss was just a teaser for a future update I'm working on.
I had plans to make 5 bosses but this grapple/ swingshot mechanic was a bit more difficult to code than we originally thought. ^_^"
And I am working on adding some more attacks for each boss, even the first boss.
Hopefully with all the updates and improvements I have in mind, it will make the game a little more fun! :D
Thanks for playing and providing feedback!
