I want to start by saying this is a super cute/sexy mod, the mechanics are interesting, I really enjoy it.
However, I have noticed a few bugs/feel-bad mechanics
the bounce calculation doesn't seem to work quite right. If buxom is single-digit, it only increments the Bounce to your Buxom level, so you won't get any statuses unless you raise Buxom over 10
If you gain a large amount of bounce at once(10-30), it will immediately give you twice as many bounces as you should get. I am not sure if this is true with regular bounces as well, but it is definitely true with Big Bounce.
White Bikini gives you a Broken Bra card, but the others do not. This seems to be true both if you grow out of them or put one one that is too small. They do all have the broken bra cards in the compendium, but they do not show up in game
AN upgraded White Bikini or Omega Library will give an upgraded Broken White Bikini or OMEGA Library, respectively, but the upgraded versions perform identically.
When you get the Exposure condition is a little inconsistent. Cards with Expose do it reliably, but the tooltip(and the art) say it should happen when you reach 20 Buxom, and it isn't making you exposed until 30. the only exception is if you play a card with Expose(which work correctly) or break a bra, which will expose you at end of turn, leaving you vulnerable without letting you benefit from the damage
Cards that do damage based on your Buxom, like Bouncy Exercise and Omega Beatdown, do not scale off of strength or vigor, but do still consume vigor
And finally, the tooltip for Steady Lactation is broken

Anyway, hope this was helpful. I enjoyed the mod, and look forward to the next version
