If Bloodstained wasn't quite the same, but instead...

My jump into 3D games has been difficult.
I always have an apprehension when it comes to character+camera controls even if at least tank controls are about unused nowadays.
Fixed camera rail game-style is easier on playability but of course hampers freedom a good deal, the same goes for enemy lockdown.

I am fine with a 2.5D game, really. I am not nostalgic of pixel art even if I always appreciate games that have it.
For me, the most important part is the playability and overall balancing. Another one is the absence of fatal glitches/bugs.

After that I am pretty open to anything, as long as it's compelling enough.

I am also used to the grinding (blame RPGs) as long as you don't die in a cheap way because of relentless opposition.

As for Master Iga's way of managing the game, I'd be pretty confident he'd want to do his best like now. That said, the end result is never guaranteed until the foundations of the game are made pretty solid. Let's just say I'd be confident still, like now for our little 2.5D 'stained.

I love IGA's 3D Castlevania, and Curse of Darkness is one of my favorite, but they objectively had issues especially regarding the graphics and level design. I wouldn't be as excited as I were for Bloodstained also because IGA has got less experience in 3D. Having loved Lament and Curse, however, I would still get it.

I'd be interested for sure, but not as interested as I am now. Lament of Innocence and Curse of Darkness were both good games, albeit with significant flaws. Nano Breaker wasn't so great but I'd be willing to give another 3D game by him a shot. But yeah 2D gameplay was the preferable choice for him.

I'd be in wait and see mode. I might still have backed it just to support IGA, but it would have been at a lower digital tier.  I certainly wouldn't have pledged for multiple platforms.  I really just am not a fan of the 3D Castlevania games' designs.  To be honest, I think Castlevania 64(I never played the Legacy of Darkness version, so I can't comment on that) was the best of them because at least it was trying(albeit badly) to replicate the 2D games' gameplay.  IGA's 3D games got the atmosphere right, but they just didn't play like Castlevania to me.  I can imagine my feeling towards those games being akin to how some Oldvania fans feel towards the post-Rondo games.

i would still get it for 5 reasons!

1. To support IGA and Miss Michiru
2. i loved Curse of Darkness
3. if it has Michiru Yamane as the soundtrack composer then shut up take my money and let me listen to it
4. i would be interested to see IGA make a comeback to 3D games
5. if all the scenario was still the same then take my money. young girls with swords and magic + alchemy + demons = profit

BUT! no... it would have been a mess and im sure those amazing 5.5 millions would not exist if the game was 3d oriented and a few reasons of why i think that are the next:

1. NOSTALGIA SELLS: lets face it, while hardcore castlevania fans would have thrown their gold at iga (like me) many people donated because of nostalgia and the god ol days playing 2d sidescrollers but most importantly a true castlevania game and 3D igavanias are obscure titles with lots of critics and hate not to mention underrated.

2. SOTN and ARIA: Correct me if im mistaken but these two games in particular are the ones that made IGA a superstar, specially SOTN being of the most popular games in history and people want more games like these two not like LoI and CoD and guess what! bloodstained its trying to emulate those two and to our pleasure its doing it just right.

3. THAT KICKSTARTER PITCH: having a game developer with EXPERIENCE making games talking about his ideas sure make lots of people hype but if you remember iga talked about game companies rejecting him and his ideas that were all about 2d games so if the game was supposed to be 3d then im sure it would have been a very different story.

4. KONA... cough. lets just say a lot of people hate a certain "gaming" company for many reasons and one of those reasons was not letting Game developers do their work right. Having an ex developer to succed with a 2D game wich was something that im sure the corporates of this certain company considered unprofitable and old, would have been a slap in the face for them and not only them but also to the other companies that closed the doors to a very humble man.

so forever happy that ROTN is not a 3D game nor a fully 2D game. 2.5 its just perfect. 
fun fact. Lords of shiz was a pretty popular game that while it had nothing of igavania it actually made the franchise more popular by the time it came so maybe that could have affected a 3D igavania game with positive results. (dont get me wrong, I HATE those games)

I would be fine with it loved the 3D games, but I prefer 2D myself.

2d metroidvania also has the bonus of attracting the fanbases of other indie games looking to catch that sotn magic.

"Here's how the man himself would do it."

Bloodstained certainly has the looks for a 3d game, but I don't think it has the following for such a transition, not yet.

There seemed to be a lot of vitriolic criticism regarding Castlevania 64 which I thought was a touch harsh. Yes, it had its flaws but, generally, those defects didn't really spoil, what was, a whip-cracking, spooky adventure.

The game infused a feeling of loneliness that made it all the more eerie. Occasionally, the hairs stood on the back of my neck whenever I was very low on life and stalked by the nasty vampires that'd wait for you in certain areas. Those vampires would chase you relentlessly and make horrible noises as they lunged. The chainsaw-wielding Frankenstein in the garden maze was menacing. Stained-glass knights, skeletons on motorbikes, an epic fight with a behemoth, spider-women and blood monsters were just a few enemies that kept you on your toes.

Personally, I found Castlevania 64 a tad more creepy than Symphony of the Night. I loved it!
