Thank you, I'm glad you liked it!
If you unlock all the gems, you can get close to maxing out changes, and if you complete all endings, there is a sandbox mode which allows you to control all settings. Spoiler warning, but you can find a guide on how to do it here: https://desidee.itch.io/changing-time-vr/devlog/754383/ending-list
As far as new changes, I only plan on adding some QoL changes from here out, no new content. Instead, I'm working on the next game :)
