• I won't be going ahead with the Hearts of Power system. As much as I love the concept, I'm not skilled enough to code something like that and I'm pretty sure it would be a nightmare to balance. Instead, I'll be giving each character a Blazblue-style Unique Ability. Unlike CvTW, however, this won't be tied to an extra meter.
• With the removal of the Hearts of Power, the name of the game will change from Capcom Heroines: Clash of Hearts to Capcom Heroines: Hyper Fighting Frenzy. Since the original title was a reference to the Hearts of Power, it doesn't make sense to keep that subtitle without the major gimmick. The story of the game will also change.
• Heart Surges will now be replaced by one of two possible options when your life is less than half. Frenzy Mode is a Pandora-style boost in power, while the Hyper Combo is a last-ditch desperation attack akin to the Exceed in SVC Chaos.
• I've decided to go for the MvC-esque gameplay rather than trying to ground the game to an unneccesary degree. It'll be heavily reduced from ost "Hyper Fighting" games, but a lot of similar concepts - air combos, wall bounces etc. - will remain.
• I'm debating as to wherever to put an "Easy Combo" feature on LP akin to MvCI. Discuss.
• I'm also wondering wherever to drop the universal Launcher button. The reason I put it there was because I have a nasty habit of holding down on the control stick during air combos and thus accidentally ending them when I don't want to. But if this isn't a problem that most people experience, I'll shift it to, say, DF + HP and remove the Launcher, making this a 5-button game.
• There's been a lot of good character suggestions on here, but I'm very hesitant to add them because I don't want the roster to grow much bigger than 10-12 at the moment. While I may tweak it at points, that's as big as I want to get, and unless I change my mind about having the guest character, I might not be able to please anyone. Maybe some characters will appear in an update, I don't know.
• As hilarious a concept as it is, Miss XYZ will have to go. The sub-boss will either end up being Ingrid, Decapre or Juri. Juri might end up playable, I don't know.
• I think I've seen some half-decent sprites of Delta Red Cammy in CVS style. Can anyone confirm that for me?
• Even after I said what I said about Roll, I'm considering dropping her for the moment. Her tiny sprite size might cause problems unless I do some scaling tricks or shell out for updated sprites and I'm already going to be throwing a fair amount of money at Rouge.
• Should Jill go? Or Saki? I feel like these two overlap a fair bit due to being "gun girl" archetypes, and while Saki does a lot of different things, I don't want people to complain the roster is nothing but gun-focused characters.
• I wanna try using MUGENHook to implement a few neat screenpack tricks, like animated characters on the select screen, character portraits sliding in on the VS screen etc.

For characters I think Tessa from Red Earth or Pure The Mage from Adventure Quiz: Capcom World 2 would be decent "witch character" additions and good replacement for Rouge at the moment.

For villain characters you could use Devilotte from Cyberbots, Ton Pooh from Strider and Juri from SFIV who I don't considerate a villain but more of an anti-heroine.

You could always do a "Terry", quick spriting Edward into a female edition. 

I'd personally drop both Roll and Amaterasu, since Roll is tiny and Amaterasu is, well, a dog.

Oh, nice work on the screenpack.

How about Ruby Heart?  I always liked her and she's pretty much doomed to be MvC2 exclusive.

As for Roll, since you're willing to do commission, you may want to consider this: https://mugenguild.com/forum/boardseen./topics/new-roll-sprite-sheet-capcom-universe--192454.msg2501344.html#new

I'd be willing to pitch in with the commission as well. The guy there mentions an incomplete sheet. If you could acquire said sheet, and depending how much is done, it could end up reducing the price a fair amount. I...may be willing to help with coding... My interest in Mugen has been waning to say the least. However, this peaks my interest. If nothing else, I could test and provide feedback. We'll see.

Replace her with Gladia's Michelle Heart. I'm honestly surprised you don't have her here for this. Did you do all this SP concepts yourself? It looks very nice. Very aesthetically pleasing, easy on the eyes. Seeing that Revelations render of Jill makes me sad there isn't actually a sprite set with her in that attire.

Private I’m afraid. It’s locked to the unreleased Capcom All Stars full game and as such is not available for anyone to use until that game releases. ;-;

• 5 buttons overall. Four for attacks, onefor special abilities.
• Fifth button will serve either as a "Unique Ability" or as the "Surge" mechanic (name tentaive), which has both offensive and defensive uses.
• Combo progression runs on typical Marvel/Darkstalkers lines: LP > LK > HP > HK. Gameplay is essentially "Marvel-lite", featuring a toned-down version of similar gameplay that still provides flash without leaving room for "touch of death" or "infinte" situations. Launcher will be a universal DF + HP command.
• Classic 3-tiered Super Gauge. Characters will either have two Super Combos and one Level 3 Hyper Combo, or two Super Combos with enhanced "Surge" versions.
• Movement will consist of dashes instead of runs. Super jumps and short hops are also available.
• "Easy Combo" on LP, akin to MvCI/KoF XIV.
• Advancing Guard and Guard Crush. A Guard Bar will be used as a resource.
• "Rage Ultra" mechanic inspired by Tekken 7, SvC Chaos and Mortal Kombat 11.
