Hi! Thank you so much for your interest in the bundle! 😊
Yes, you’re welcome to use it in commercial projects, including Godot games with optional 18+ adult content.
The standard bundle includes PNG files only. I’ve also added an option that includes the PNG bundle together with the Inventory & Diary PSD source files, so you can purchase them together. PSD files are included for Inventory & Diary only.
During the current sale, you can get this option at the original PNG bundle price.
If you have any other questions, please feel free to ask. Wishing you all the best with your game!
