Do you need the newline in the text of the token? You could try removing
fragment from the NEWLINE rule and then setting it to the hidden channel.
Then have your lexer rules match everything except the new line characters.
Like this:
MC_QUESTION : INT ('.'|')') ~('\n'|'\r')*;
MC_INCORRECT : LETTER '.' ~('\n'|'\r')*;
MC_CORRECT : '*' MC_INCORRECT;
NEWLINE : '\r'? '\n' { $channel = HIDDEN };
fragment LETTER : ('a'..'z'|'A'..'Z');
fragment INT : '0'..'9'+;
I'm kind of new at Antlr too, but I think that would work.
