I know it's a little late, so hopefully you've already solved it, but it looks like in Game.java, you typed hit instead of hits in your getCurrentProgress method:

if(hit.indexOf(letter)!=-1)
//   ^ should be hits

In the future, try formatting your code with the Markdown Cheatsheet. It makes it much easier for others to read your code, which means they're more likely to spot what's wrong! In situations like this, where there's multiple files and a console involved, it can be helpful to create a snapshot of your workspace, too.

Hope that helps!
