Thank you for your support!
For now I've planned 5 size levels (0 to 5) for this game, and the last one will probably be pretty big, sorry for the inconvenience.
On the other hand, I have plans to add a device or method to alter your size, allowing you to see the applicable events with any size you want.
I plan to add stats like cup size for the main character too!
I have purposely disabled the return button, as I don't really like the "going back" thing in that kind of game.
If you really want to use something similar, you can save before a decision and load if you dislike the conclusion, but I think that having the "size altering" method will alleviate these problems for you and others!
I like the feeling that the "Go in" and other small steps give, as it feels more interactive, but I may change it if I see that it is widely disliked.
