Ok, I finally got the console and the game with it. I have played it for almost 5 hours (the first con: and almost completed the whole game), but I’m still not sure am I liking it or not.
I’m going to be talking about the 3D effect the most of this impression, because it was the most interesting addition to the game.
The 3D effect is totally new to me. I do have watched one 3D movie, but that was long time ago. The problem is, it’s really hard for me to see the 3D effect. When I first turn up the 3D, my eyes start to really hurt, and I see one picture and two faded pictures on the left and the right. And on the very first time, I even felt like I was gonna puke. Then, when I turn it down a little bit, to the point it matches with my eye sight, for the first few seconds it looks amazing, but soon I forget the 3D is on, because the effect is so low and it starts to feel like I’m just playing the same old R2 again. I turn the 3D up again and I get a headache…
Yes, there were moments, where the 3D felt just amazing, expecially on the Whales Bay level and places, which had huge backgrounds and just a few things floating beside Rayman.
There were added some stuff for the 3D effect, like bats flying towards you, but for me those additions didn’t work, because the only moments I couldn’t see the 3D at all was exactly when something was close to the screen.
But it might be just me. My eye sight isn’t bad, but maybe the 3D just isn’t for me. So if the 3D would work in all parts of the game, I’d say this game is perfect for the 3DS. Like on all versions, theres always something coming right at you, or you are just moving forward fast in a tunnel while avoiding aproaching objects and THAT is where the 3D really should look great.
Oh, and I read in the 3DS’s instructions, that your eyes just needs to get used to the 3D effect. I have only played for 5h, so my eyes maybe have not gotten used to it yet. And I forgot, that before turning the 3D on, you should make sure you aren’t feeling weak anyway, like tired, or even hungry, because first time I played, I had arrived from a long trip and I hadn’t eaten for a long time so that’s maybe why I felt really sick when trying the 3D effect.
There isn’t really anything else to talk about it… there’s really nothing new. Only thing that was new for me was the ISLE of doors, because I have only played the PC and the DS versions.
The slidepad felt great, but the jump/shoot/dive/target lock-buttons were wierdly placed.
Oooh, and the music was just as awesome as always and not just some lame midi sounds like on DS version. Speakers sounded amazingly great, but they got a little ”distorted” if I had the volume level set all the way up. Some of the sound effects, like when Rayman screams while swinging on purple lum, were changed so that you hear them maybe a bit too much.
Framerate dropped sometimes (well, actually really rarely) so low, that it was a pain to play the game (expecially when 3D was on).
There weren’t a lot of glitches, except one major in the Tomb level (SPOILERS?) in the secret area where you could get the ”dead lum”: when I beat all the Henchmen, and when I tried to jump into one of the giant skull's eyes, the web trampoline didn’t do a thing. It was just a hard plaform. I couldn’ reach it, but then I found another way to get there: when you have all the platforms to get to the skull, kill your self, go near the reappearing henchmans, jump and let them shoot you when you’re in the air. This way you will be pushed just a little higher, so that you can get into the eye. But then I came across another glitch: after I got the lum, when I tried to jump down to go forward on the level, Rayman just froze there. All I could do is press start and restart the level. Luckyly I kept the lum I got from there. I guess the spider web was made solid on purpose… but I have no idea why…
Other glitch I remember, was the lavafalls going invisible for a second in the flying level.
I’m not sure about the mysterious hole in the Tomb level. The wall it used to be on was completely dark and you couldn’t set the brightness any higher..
Globox village might’ve been removed. I’m holding on a little hope that you can get there after beating the game.
Umm… maybe two more things comes into my mind:
I might repeat myself, but the areas have been made a little more alive by adding new stuff, like frogs and bats and using the old stuff more, like the flies from the beginning of the game and those yellow and blue butterflies (wait, were those in the original? or are they reference to the Rayman M?? O.O

)
Ooo, and also, Rayman does the tongue thing, like in R1 and 3, when you stand still for a while.
And finally one more con: The game is hella lot easyer than the other versions I’ve played. For each hit, you lose like half of the health you lost before. And…… if you die instantly, you regain your health back to full… o.O
Half of this post might’ve been pointless to the people, who have played the Dreamcast version, because the additions in this game might have been different just from the PC and DS versions, but not from the DC version… so sorry about that.
I guess thats it… my english kinda sucked on this one…
