Since no one is visiting the temporary forum anymore, I will post my impressions here.
These are the impressions I have spending about 1 hour playing the game.
I've played about 2 stages and half and will talk about my impressions on this game.
About the story, there is a prelude kind of scene featuring screenshots from the NES games, and texts accompanying saying that Dracula have been once again revived and Christopher is up to save the day. Nothing special. After that, I haven't encountered any story telling scenes.
The design, at first glance this game looks alot like the X68k title and the MD title combined, the character sprite is well done, Chris moves a little bit like Richter but generally he kinda resembles Simon in X68k. The stage layout has been completely changed from the original Adventure game, though there are some elements remained. Such as the tiny platforms with huge gap in between and the floating platforms. Most of the emenies have been redesigned, like the crow, the thing that spits out a ball which attacks you.
Bosses are comepletely new. One thing I need to mention is that mid-bosses have been added, like when you have progressed about half of the stage. The first mid boss is the classic giant bat, the second is a huge slim. First stage boss is a super large bouncing eyeball which can grow out little eyeballs rolling around(you can only kill them by crouch attack). Second stage boss is a mutant man which can throw rocks at you, he can grow buffed like Hulk, and can turn back and looks like a skinny guy and jumping around.
Classic sub-weapons like cross, dagger and axe are as effective as in old school castlevanias. The fireball whip in the original game have been altered, when you get hit you can still have it, only there's a time limit, it's the green bar just below the health bar. When the time ends, your whip will go back to a normal chain whip, until you have got another power-up later on. You can have only one fireball on the screen which means you can't swing whip multiple times and try to make bunch of fireballs like in the oroginal game.
Controls, you can change the direction while jumping now though the facing direction will not change. the attacks seem fluid, though there are only two buttons available, whip and jump. You can't change the whip's direction like in Super IV or Bloodlines. Also, after I quited to the title screen, a message saying an option called "Player Style" is now available, I tried to set the style to classic, and now I can't change direction when jumping, dunno about other changes though.
Now, the music. It seems to me that the Sound source or sound chip is the same as the other two rebirth titles, so it sounds a little bit like X68k, the arcade and MD combined. The music track in the prelude is the music plays during the map demo on Dracula XX SNES, dunno the title. Every stage beginning a short tune will play which originally from the very beginning of the Vampire Killer on the X68k title, then followed by the actual stage BGM. The first stage BGM is "Reincarnated Soul" which I dissapointed a little about not being "Battle of the Holy" it was suppose to be in the original. Second stage BGM is "Sent to the Devil's Requiem" from Haunted Castle, it sounds a bit strange for a stage BGM though. The third stage is "New Messiah" from Belmont's Revenge.
According to 2ch, there are 6 stages, and the BGM for the rest are
LOAD BGM from X68k
Aquarius from Castlevania III
Vampire Killer from Castlevania I
update:
Stage boss bgm: Final Battle from Haunted Castle
Map Demo: Start BGM from the original Adventure
No stage BGMs from the original Adventure title as 2ch gamers stated.
Also, there are hidden rooms which you can only access by aquire a key as a sub-weapon, same as Rondo. Rope actions seem to be cancelled accroding the 2ch gamers. When the game starts, a map screen will apear, and Chris will walk through the screen just like the classic Castlevania and X68000 version, kinda nostalgic? There are also alternate passage ways exist which some can not be entered for certain reasons, maybe a switch or a key somewhere....
There is no save option, once you exit the game and return to title screen(or wii menu), you will have to start all over again, however, as stated in 2ch there is a stage select option somewhere, and maybe triggered by pressing right and start at the same time during title screen, I need to confirm this later on.
edit: at the game select screen, put cursor on "game start", then hold right on the direction pad for a few seconds. There you go.
Overall, it's pretty decent, aside from the letdown which it's not a exact remake of the original like the first Chronicles.
