Thank you for playing! After playing a bit with it, I decided scraping the old "new" combat system as it would make fights too long. The last thing I'd want is to make fights too long and boring. That's why I decided to keep the old one with the new design and animations!
Length, cum and bust have visual changes in the Stats screen. They're a bit subtle, though. The difference between Level 1 and, say, Level 80 is very noticeable, though.
Thank you for letting me know. It is very hard to optimize the game as I can only really test it on my own machine. This data helps a lot. I will also look into the audio issue you mention! It will be a priority as it sounds very annoying.
That's the goal, yes! Having a number is better too, since I have a measurable, specific objective to follow!
That's really odd... If possible, let me have a look at your save so I can address the issue! This way we can avoid it happening again in the future too.
