A story about killing a dragon is probably self explanatory enough it doesn't need to be explained in too much detail, but just a bit more introduction and set up wouldn't have gone amiss.
Some punctuation issues, but I'm assuming this is all a first draft and you're planning a good proofread, so I won't nitpick there.
The writing itself is not bad at all. I'm not a huge fan of that style of humor, but I suppose that's a subjective thing, and I can at least tell you were having fun writing it. Are you planning to expand the path right where it cuts off quite a bit further though? All the others cut off so quickly and it's going to be a very, very short and pretty linear game without that.
