You hit the Lavender nail on the head there, haha. Her natural lack of confidence (despite her natural competence) is only amplified by her... unusual circumstances. No spoilers in case you haven't played her story scenes! And yeah, I definitely did my best to make characters' decks match their personalities - both at the start, and over the eventual course of their character arcs. Like all the Lyons Cubs, Lavender can become terrifying by the end of the year, haha!
Thanks for the bug reports, these were really helpful - a couple of Retain bugs have already been fixed in the dev build, which argues that I should probably move up the next public release so they don't keep hitting users.
I definitely appreciate your diligence in tracking down the tripling issue, which is very real and still present in the dev build. The simple explanation is that I forgot to include a conditional statement so when a character's AI is evaluating playing a Super Strike/Struggle/Squeeze/Massage card, it'll actually trigger that effect. Boneheaded mistake on my part, haha.
Still trying to figure out the miscellaneous calculations - would take some effort to add a "Combat Log" feature showing the nitty-gritty details of how everything was calculated, but as the game grows more complex it might be worthwhile.
