Jesus...
People shouldn't base a sequal of a game just because they liked the old one better. They should be focusing on the game itself.
I liked it, but the same problem with the other ones: Alot of random shooting.
Then again, there isn't really a way to make a game like this more puzzly.
It was addicting, I got to level 40 ish and then I got a intermission which bassically froze or something. SOOOooo I quit there.
And as for the old graphics being better, I find them samey. Not impressive eiather way, and I don't really look for graphics in a game.
Overall, 8/10 and 4/5.
