simply amazing
I'm usually not much of a fan for gory stuff, but this is amazing. The graphics are top notch and the effects are very good aswell. To add on, the plot is very intriging and is surprisingly complicated.(as a suggestion, I think you should do a remake of castle 1, it doesn't fit in with the lesser graphics and no dialog, and you could also make it to fit the plot better aswell). Groundbreaking flash series. I still can't begin to express how awsome looking the graphics were.
As for plot questions you wouldn't mind answering:
1. Did you decide to forget about him being bitten by the zombie or is that still a part of the plot?
2. What was the point of Lyoid I think it was dying( he was the one crushed by he rock right?), I didn't see the reason for that, but thats just my opinion.
Other notes: I really like how you made the nameless soldiers able to defend themselves, most other nameless soldiers end up dying immediately with just a few living. I also appreciate the added effects that most people don't notice, like how sad the general looked after he shot Etrius. The voice acting was excellent, and so was the sound effects and music, that random rock song fit pretty well. There's not much I can say negative, so I'll leave it with that, good luck with the next one, I'm guessing Castle 4.
