Bloodstained has fixed 1 critical issues from other Castlevania style, while at the same time having other issues.

Why you would enjoy Bloodstained:
Gameplay:

- Rich magic casting, shard/souls system -> Allowed you diverse your gameplay. These spells can also be upgraded, crafted into a new spell completely.
- Technique (weapon art) further improve gameplay style. Majority weapons come with secret skill, technique, using it is very much similar to input combo skill in fighting game. When you gain enough exp for a technique, it is then unlocked to
other weapons with same type. However, Bloodstained makes it quite difficult to execute those combos via controller consistently compare to keyboard. (Meanwhile, it is the reverse with fighting game)
- Nerf healing: Many other castlevania game can be cheesed with lots of healings, not this one.

Having rich experience in other castlevania style, I ease through bloodstained in normal difficulty with ease. Compare to other Castlevania, Bloodstained can be regarded as one of the most difficult by actively nerfing healing option. Beside limited amount of healing you can bring, crafting healing is also expensive, spell that can provide healing often close to useless.

Spoiler warning: Reading the spoiler will make the game becomes too easy. One the key issues that make this game easy, is how overpowered jump kick is in Bloodstained. Majority of bosses is extremely weak against jump kick by having no skills that can counter repeated jump kick

Story: You don't come for Castlevania style game for story. It has always been lousy and cliche except for few entries in the franchise. The story of bloodstained is good at world building, creating potential hype for future games. Meanwhile, characters development is as cliche as it can be, and you feel little to zero compassion with the characters.

Music: Truely a masterpiece, you dont feel bored with the music and found them seamlessly flow into you. There is no epic soundtrack, it just naturally poured into you.
