Personally, Good game... some bug, but nothing to critic
One transformation idea would be: Milk-tank/Cow girl (Secret Transformation)
how to obtain: Getting 50 milk, and after 99 milk (explained below)
Visual change: Your breast get even bigger, your nipples get inverted (basically Voice 2.0), and your ass and hips get slightly bigger. (maybe another extra detail to show more the "cow" state, the hair will change to white with "your actual/transformation hair color" spots)
Context: If you get up to 50 milk (that isn´t easy btw), you will get KO by the weight of the player breast. Voice find you and decide to train you to be able to walk again with the extra weight (that why the bigger ass).
If after that (and still having the first version of the transformation) you get to 99 milk, your breasts will be as big as your body, making you unable to move once again (and getting KO again), but in this case you have that amount of milk that it start to leak, attracting the attention of Catgirls and even the Werewolf. Voice save you once again, but she decide to milk you the extra milk, because there is no way that any training will make you walk with that weight. after that, both KOs will no reappear if you don´t subtract the transformation.
Effect: this secret transformation will not and will not be override by other transformations (the setup to getting to 50 and 99 milk is very difficult to be lost in some KOs).
this transformation will give you 3 abilities that regen over time and one utility:
Breast massage(utility/heavyweight): gain 4 milk each use
Breast Squirt: use 2 milk to shoot milk to enemies, damaging then in the process. the more milk you have, the more range and damage dealt (-25 = 1 tile/1 damage, +25 = 1 tile/2 damage, +50 = 2 tiles/2 damage, +75 = 3 tiles/2 damage, 99 = 5 tiles + spread/ 4 damage)
Breast Feed: use 6 milk to heal you or a foe 3 health (at 99 is unusable)
Breast Slap: use our breast weight to damage enemies. the more milk, the more damage (-25 = = 1 dmg, +25 = 2 dmg, +50 = 3 dmg, +75 = 4 dmg, 99 = unusable)
Passive: A property of this transformation is that give you +10 Max Health, and make you regen milk until a cap (v1 = 2 milk/5 turn/50 cap, v2 = 5 milk/5 turn/99 cap). but, the more milk, the more weight you have, making you slower (-25 = 4/2 movement cap, +25 = 3/2 Movement cap, +50 = 2/1 Movement cap, +75 = 1/1 Movement cap, 99 = Unable to Move)
At +50 milk, all milk abilities will transform into Heavyweight. at 99 milk (if you already get the KO), you will be unable to move, any mobility ability or utility (even struggle) cant be used, some milk abilities are unusable (Breast massage just do nothing), but Breast get extremally strong (but still heavyweight btw).
