Traversal mechanics (Submitted)

My guess is when in the air your second jump can be in one of the 8 cardinal directions. Like jump up, hold down, push jump again, to speed to the ground.

I thought that, too.

Like Julius' "Comet Kick".

You're talking about the Air Dash, aren't you?

The Double Jump function in those games only works with the 3 Up directions.

Wings and flight are a must for me. Doubly so if you can fight while flying, or have unique moves while airborne (dive bombing and sky dashing)! These are always awesome, and were done very, very well in Order of Ecclesia. Each character could have different colored wings, to reflect their outfit or personality, or a totally different mode of flight altogether.
Mounts are always fun, but are usually solely there for aesthetics, or to traverse spikes (though maybe a healing mount where some creatures carry Miriam would be cool).
High, double and triple jumping is a must; as are dive kicks and teleports.

It could even be an Ability gained from a certain enemy who drops the necessary magi-crystals needed for Alchemy (the crafting system that we'll have in Bloodstained).

I actually suggested this not too long ago in the Ideas for Enemies thread.

I've been really into this game for the past week. It takes the igavania recipe and does combos beautifully. One of the best features in this game is the ability to use a skill that, when timed correctly, let's the player "slide" through enemies and damage. I don't know if this would work well for bloodstained, as valdis story works off the idea that enemies usually take multiple hits to kill, but it's so fun when playing it.
Also, a boss ranking system. E. G. Don't get hit too much, get a better rank in that category. How fast you beat the boss is another rank, and not using recovery items. These three ranks average to a final boss rank. Depending on your boss rank you get a permanent bonus to a parameter point, or more hp, or an extra skill. These are a few things I would love to see in bloodstained. What do you all think?

I stopped playing it after the second boss or so. In order to do well in the game, it was going to require more work than I was interested in putting into it ...

I liked the idea, but I had (and still have) higher priority games with which I'd rather invest my time.

I think he was talking more about Valdis Story mechanics/ranking systems in general than just movement...but regardless, I played a good bit of the game and liked it. It felt more Metroid and action platformer (i.e. Mega Man Zero) than a Castlevania game. I think the elements unique to it work better in a game centered around its almost fighting game-like combat system. Iga's games are more about weapon and spell variety, finding a favorite/strong weapon against a particular enemy and then moving on to more weapons, not so much mastery of a handful of skills in a tree, timed inputs, guarding, etc. He's gone on record before that by necessity the game is slowed down in these cases by including "hard" enemies (not hard as in difficulty, but "hard" as in a rock in your path/an armored obstacle).

I like difficult games myself and I'm definitely into fighting games, but Iga's games are something different.
