To unlock the cage you need to speak with Rayne and ask her for it when she is working on her computer. Affection must be high enough. If you mean Jessie, you meet her in the clinic for the first time and then you can see her in the gym.
I'm fine, thank you. I have plenty ideas, not the time to make every of them into the game probably. But you can bring yours, there is suggestions section on my discord server. I read them all and take my inspirations from them.
I've been thinking about implementing some 'upgrade' which you could obtain to see the energy cost, though I don't really remember an action which could take 13 energy, what was that?
Before 0.5 you can get there trough police station, if your relationships with Rayne aren't too high, after 0.5 you can also get there trough progressing main story trough choices in conversation with CEO
Not sure what could be causing the issue unfortunately. I'd suggest to try different settings of skipping in "options" tab of the game and try different render engines in Shift + G menu.
I didn't have any reports of problems like that so far, so that must be something on your side.
I need more info to guess what could be causing the issue. Your platform, if there is any error messages when game crashes and what exactly happens during animations.
You can gift both to Rayne, if you don't have enough credits by the end of the week. If you gift the dildo, additional scene can be triggered with Rayne using it in the shower. No additional scenes for the vibrator for now.
Sissification /Feminization fetishes will be included. Mostly as part of one of the characters routes. Full male to female transformation is unlikely though, as and mpreg. But could be included as one of "bad ends" at some point.
Thanks for the feedback! Yes, I'm certainly planning present the backstory with images in the future. It was actually created as one of the last things on the game, so I decided to leave it as text version for now.
