Just beat Land of Dragons....took me 10 hours lol
so far my impression is
-the visual looks gorgeous. The KH's artstyle really helps when it comes to HD remaster.
The image looks crisp and the AA isn't as noticeable as the screenshots. But I felt similar with 1.5 remix so if people were not impressed with 1.5 I am not sure about 2.5 I do feel 2.5 looks better than 1.5 but it's because original KH2 looks better than KH1.
-The rearranged music is great. Unlike FFX HD, It keeps the feel of the original, while improving the quality. The world map music is soooo good.
-I haven't encountered any sorts of bug/glitch so far. If there was it was something very minor that I didn't notice it.
2 negatives things, and these are very very minor issue, I have so far.
-The left side of the UI doesn't look as sharp as the rest of the UI. Some parts of the UI look kinda blurry and upscaled. It depends on which world UI you use. Of course it's very minor thing and nothing that really hurts the overall experience.
-During the gummi ship part, the bgm and warning sound is really big so I can't really hear the sound of my bullets. I don't remember if this was the case with the original KH2. It's really hard to hear the bullet hitting the enemy so I can't really tell if I am hitting the or not.
I am really enjoying my experience so far. I forgot how much I loved KH2.
