Heya. Thanks for reaching out. Honestly forgot all about this game, but I went and tried the new update.
Game is much MUCH better now. Enjoyable, though still what you expect of a match 3 game and nothing really all too unique. It feels like the classic Newgrounds flash ones I played in 2003. That's not a bad thing, by the way. Balance is definitely fixed, and I greatly thank you for making Rias free too. I was able to complete all of Rias and the starter chick's levels with 3 stars for every level just now with only having to reply two levels I got less than three stars on and only having to use one mallet item (because the level started with zero moves but didn't shuffle like it was supposed to - I assume because it was the starter setup and I hadn't moved anything prior, so the game's mechanics got confused).
That music though... I swear I've heard it in a few 'spot the difference' or jigsaw puzzle or solitaire or hidden object games. "Pulsing soundtrack" is in your description. Maybe change the home page's definition there, as the music is sleep-inducing, and as I said before, your entire home page for the game is all "HIGH-OCTANE GAMEPLAY AND SOUNDS!" Which, not exactly the words I would have used for a match 3 of any kind. But especially not for lo-fi music.
I noticed you can upgrade the females using coins. I did so to Rias once, but it didn't seem to make a huge difference, and once you beat the levels for them, there is really no point and you baiscally waste your coins you could have used for gacha pulls. So, it got me thinking... you wanted suggestions? How about a way to utilize unlocked or completed characters as maybe a passive bonus? Like, for example, getting all stars for Rias could let you set her as a support character that gives a bonus to hearts shattered. Then, the upgrades you have on Rias could add another 1% boost or something to that effect. Then, it wouldn't be a waste to upgrade them with that new feature, and it would open the door for you to make a new mode that is like an end-game mode where you need to strategize your team and buffs to be able to win in a "match this color - all others give less points". So, what I mean there, is say you had a level that the focus was shattering pink bows. Having Rias and the heart point boost buff she gives would make the hearts debuff weakened. A feature like that would add more incentive to go after other characters and collect them all, as well as to 3-star every level and replay some for money.
Definitely find this layout much easier on the eyes, especially for the gacha game aspect, by the way. Navigation is much easier to do, and aesthetically has a very nice design. Nothing is really confusing to find, as it is all right there in front of you and not cluttersome.
Any plans to add Akeno or any ZZZ characters like Remielle or Astra to the list of chicks?
Edit: Zero Two / Viper, I think you need to swap the perk and flaw for level 15. It is literally impossible to even 1-star since you have a bonus for precision hits in a level that has none possible, and a -50% deduction for cascades, in the level that can only have cascades.
