The game is borderline unplayable for me. The whole game drops to 1 FPS if I so much as go near an enemy, and in a game that relies on fast reaction time that's not ideal. It sometimes doesn't register my inputs, especially with the traps, and sometimes refuses to let me access the menu. These problems don't go away even when playing on my PC, and it can play every other game with no problem.
What makes it worse is that so many people are gushing praise about this demo. Guess this is just one game I'll never get to enjoy...
