Good game
I really enjoyed playing this the first few minutes, but I have to admit I got bored quick due to the extreme repetitveness of the game.
The graphics were pretty good, especially the menu screen. I know it involves vampires and such, but the actually game was a wee bit too black. The gun sounds were really good though, I enjoyed turning up the volume and firing.
I did encounter a few problems, such as in survival mode I was still alive at just under 4 minutes, and the game ended and said "congrats you survived over 5 minutes!". In another game the upper left platform we messed up and wasn't responding correctly when I jumped on it.
Overall good and enjoyable.
