Maybe you're playing the PS3 version which has blurry textures.
I think the QTEs are done fairly well, yes you die if you miss a button press...uh hello....that's the point. You get to restart the QTE very quickly without a long wait. If you have quick and acurrate reflexes then you win, if you're too slow or push the wrong button you lose. So what do you suggest the QTE be replaced by? A cutscene where you always win?
I don't know what game you've been playing but the small rooms only have a couple enemies. It's the larger outside environments that have many enemies. Some medium sized rooms do have many enemies but it also has barracades you can hide behind then jump to fire.
I thought the mirror puzzle was kinda cool, it fit in with the ruins theme. Yes it's been done before but that was a tny part of the game anyway.
I've played both versions, but it's not only the textures. The second half is just uninspiring looking. Character models are excellent and bosses are incredible looking.
If that's the point of QTE's then let them die now, please. QTEs should enrich the gameplay experience - in this you die and see "Game Over" when a random crocodile jumps on your platform and miss pressing a flashing X. Pointless.
It's more frustrating when you're trying to enjoy the game with a friend, and they can't get the button presses - so you have to keep on doing it together. How about there's actual gameplay in these sections? Or, like Heavenly Sword tried to attempt, there's a different non-fatal outcome to missing a QTE - eg. lost health, failed animation etc.
How about the level when there's a bunch of military zombies, which is then joined by the retarded zombies with big gatling guns (the rubbish AI is shown at its worst here), and then insect aliens?
It was too easy. Where are the good RE puzzles I remember?
