Hi there!
"Gilded Cage" is planned to be a project for RPG Maker XP, similar to older RPG Maker games like Yume Nikki and Pocket Mirror. It's not intended to be a huge undertaking—just a hobby project. The game is designed to be divided into chapters if everything goes as planned. The story is already quite developed, with each chapter having its own logline.
I'm currently looking for an artist to help with sprites similar to those found in visual novels. I’ll be updating the site soon, but important details are already listed on the Carrd.
Let me know if you have any more questions or need additional information!
