There is a lot of misplaced narration and voicing in the scenes and many times that the voices wouldn't even play. This all happens after the slime fight.
The fact that the fight had sound effects of swords clinging and the vine attack had no sound effects whatsoever alongside misplaced voicing from the female protagonists was a real downer. It would've been fun to hear the sound of the vines entering them with a lot of noises like splatters, squirts, and claps from the speed of the movement. A great example of where the lack of sfx had great effect was the part where Jasmine said, "Not so rough!"
Some feedback on what I, and probably many others who are interested in your visual novel, would like to see in the future.
Try to add choices: When choosing to enter the cave or not, perhaps the characters will decide to avoid the cave when selecting no, but one of the characters decide to barge in anyways, thus resulting in everyone else following her. When the fight with the slimes is given option, you can choose to avoid the slimes. It wouldn't matter much anyways since there was simply no use of fighting them. A way to make the game extra interesting in regards to the slimes would be (as an example) to add a few intelligent foes in the deeper end of the dungeon that request that the girls pay with slime cores to pass through. Killing the slimes would mean that they are 2 cores short and 2 of the girls would be forced to stay behind or they would need to barge through. Ignoring the slimes will lead to the group to need to go back and get them or force their ways through. For the plant scene, a really great no option would've been Seashell moving away from the plant and the group move on, or she leaves the plant and another person clumsily steps on the plant, forcing in the scene in both cases.
Since the plant made them horny, it would've been really fun to see them making out with one another and maybe even pleasing each other before getting attacked by the vines. This would've appealed to the diversity of your followers and the people passing by to watch this visual novel.
The lighting and art style are really great and as expected from someone like you. I love your style but only for your princess models. For some reason your pokemon and non-princess Disney models aren't to my taste. I love these models a lot but would've loved it if the visual novel was to go to the level of these models.
You did a good job considering the fact that you decided to use Unity: "It's a decent software to make terrible games." (I am not saying that your game is terrible, but what I said is the usual outcome of Unity since there is so little you can do with it and it really limits your capabilities). I don't know how Newgrounds works but I am sure that you would make better products using something like Unreal.
All and all, I really loved this novel from an artistic pov and not from a gameplay pov. I hope to see more in the future on this project and maybe see your game on other platforms! Thank you for the effort, money, and time you put into this project, have a great day.
