Mixed indent spaces and tabs

[wildmouse]

I've found spaces and tabs are mixed for indents(for instance lines 56 and 57 of Game.java).
It's not a problem in editors but looks so strange in GitHub viewer.

@Wild-Mouse good find! Yes, this is an issue. If you would like to create a pull request to resolve it, that would be helpful, otherwise I'll go through and resolve it once more pressing issues are addressed. (I prefer tabs, but spaces are fine, too, as long as everything is uniform.)
