I had the same problem with lags and stuff. Then I installed Chrome and everything was fine, so if you wanna play this game: try Google Chrome. It may help.
Okay, now let's talk about Alice is Dead: I love the series. Your style is just amazing and the way the characters are portrayed is really good.
Although I got to admit that I'm not sure if I get the whole story fully. Maybe I should play all three episodes in a row again.
All in all, it's a totally brilliant series you created!
