The gameplay and graphics were good, especially the combat animations for the bite skill and enemy deaths.
The combat isn't too challenging if you make sure to heal between fights, though it requires a bit of backtracking.
The beginning and middle of the story were nice, though the ending felt a bit unsatisfying.
I thought there would be a final boss instead of a few waves of Rank III and Rank IV scientists.
Even with the last minute ending twist, it would have been interesting if there was a final choice of who to side with, leading to two different bosses and endings.
