Absolutely loved this! I have a soft spot for LSW but this is the first game I've seen try to emulate it. In terms of feedback, besides what was already said, are there plans to rebalance the two starting characters? It feels like Viola's kinda...weak. Her attack and HP are both lower than Lee's with the same defense, and so far their movesets are basically the same with just some reflavoring. Her ability doesn't seem as useful compared to Lee's because he can use his super move on turn 1. With Lee I won most of the game by charging turn 1, moving up, then nuking the opponent- the final boss was the only one I had to use proper strategy. Meanwhile with Viola since her attack isn't high enough to pull that off and she doesn't get enough AP to start to use her super move right away, she has to play defensively just to not keep taking unneeded damage as she slowly builds enough AP to fight. This means by the time she gets to the final boss she's usually down to half health, meaning the final shop has to be used for HP just to stand a chance (since the final boss has pretty much the same strategy as Lee does when played as him).
I think if you increase her defense so she's more of a defensive player to contrast Lee's glass cannon approach it'd work out. Give her lower attack and the same HP, but higher defense to start. I'd personally give her an HP drain on her attacks but that's probably too OP. It also would help to change up her attacks to differ her from Lee. Maybe she starts with HP drain instead of Clean Launch, or her charge boosts her defense instead of attack. It's just right now she's basically the hard mode of the game when I feel like she should just be another playstyle
