(to game author) Please read this carefully to the end.
Cool concept, interesting story, intriguing plot. Those are the positive points.
So why 1,5 star? Because everything else is not.
I don't care** that you're not an experienced programmer. You knew gaming before (Yes, I understand you were a Game Informer intern). Many new people create cool games as their first release.
**meaning: That don't matter in the discussion - I am not willing to be rude
The game: Too many bugs. Wall "climbing" (even after the fix - I have just played the game!), going outside the screen, collision detection (I kill swordsmen punching their blades, what?). Level design is simply terrible. Physics are not good, either, which matter a lot in platforming since jumps are just about half of the game (bad jumping, bad platformer).
Another bug: (a lesser one) is that the text box, sometimes, after the tutorial, won't disappear, taking a chunk of the screen and requiring a load. It's like the "falling out" bug, but it won't break the game. Changing maps won't do a thing.
You did have a nice idea, but if you work on it without at least some dedication or just execute ir poorly, as good as your idea is, the only thing that gets truly "executed" is the experience of your audience. Perhaps you chose the wrong genre (plataformer) to tell your story.
Unfinished games are not a new thing... big studios already dlivered them. Don't feel bad. But don't feel good, either! There's room for improvement.
As unfinished as it looked, it (somehow) earned a front page. Don't let that go over your head! Newgrounds already frontpaged Television-advert-pseudo-games - that everyone hated - and political flamebaits, and also denied FPaging excellent games that much people loved ("Caravaneer", the first of the two, is the perfect example - Play it and see for yourself.)
Despite all the bad stuff, the game has some appeal to me. I did go for the 3 endings after all, so I can't really say the game is too bad (I played worse games). If you dedicated more, you might have created a very good game, nearly a masterpiece. Do that next time.
Since you already know something about platforming now, hone your skill and make another. Or remake this one. Expand the plot. Try it out, distribute to friends, have them play and give you feedback. When stuff work and look good, you can start thinking about publishing it.
(TL;DR: You game is unfinished and really bad, apart from the story and concept. The game deserves 1 star in that state)
Since you fixed some of the bugs (but not wall climbing! as pointed below) it shows you actually care about feedback, and is willing to improve stuff. This earns you something (+ half star)
And as bashing as my review might look like, it's for your own good. I was once tricked by a gaming magazine from a friend to play some games that were actually terrible a long time ago. After those scandals of youtubers getting money to promote games as "impartial gamers", fills me with disgust to use the review space to state anything but the truth that everyone can experience/agree upon.
