I became totally engrossed in the game from the start. Great graphics and the music - my God, the music - really gave it a unique edge that I hadn't felt with a game in a while. Pondering map might have been enough for me given those two aspects of the atmosphere, but I did thoroughly enjoy the gameplay. At first, caught off guard, I wondered how difficult the game would be given the ease in exterminating the red blobs and the shielded brains. Not only did the puzzling aspects of it disabuse me of that presentiment, but the boss (in the demo) ended up being quite fun to take on, and just challenging enough in figuring out its weaknesses. Time flied while I ran through the temple, and by the time the demo ended I really wished that the entire game had been released. I can't wait now. It's wholehearted fun just like the kind that the best videogames can inspire.
