Just finished this today. Phenomenal work! I'm surprised as to how long it lasted, but then again that's why it was in development for so many years. My only complaint would be that in the last chapter, the game has so many battles where it throws too many enemies at you at once, easily depleting all your health & armor. But i'm sure the steam release will fix this and most of the other problems!
