Hey, guys, I'm planning on making a simple stickman fighting game on Macromedia Flash 8. Idk if it'll be tower defense or what but I need to know:

• Can I do that? (I'm 90% sure yes)
  
• Can I do it with what I know? (HTML and JS)
  
• How do I publish a game? (I don't plan on making it paid)
  
• Anything else I should know?
  
• Do I need a team?
  

And just so you know, YES, I am willing to learn a new language.
