Yeah, its supposed to be short, how long does it take to complete your typical RPG? HOURS! That's how long! How long did this one take?? Eh, bout 10 mins... So there ya go! But it was a fun 10 mins by golly!
I agree with Taali, the animation and concept are very well done. The execution is also very well done, in fact it felt more like an interactive animation than an actual game. If you were going more for interactivity than actual gameplay you hit the nail on the head. Overall, well-done.
