Bio Massacre Very good, yet I felt it could have been better
The music needs some serious work; a longer, less-obviously-a-loop mp3 would go a long way toward improving the game. No offense to the composer, but next time, please invest in better quality music.
As for the graphics, I have nothing to complain about, as I myself have not even begun to learn about flash yet. If I were to suggest anything though, it would be to make the characters more photo-realistic
Everything else (other than the fact I'm playing via a laptop..) is very good. The overall game mechanics were well-done, and I'm seeing major potential in the character dialog (I'm thinking of producing actual voice-overs for it myself).
Overall, I liked it, but some things certainly leave a lot to be desired.
