Hi there DizzY!
Thank you for bringing this to our attention and for creating your video - it's great!
To answer your question: yes, we will have a Save/Load system as well as Checkpoints in the final release. Those systems have been disabled in the demo for now as they are still a work-in-progress.
We're sorry you experienced that bug! A hot-fix is being pushed tonight that will hopefully resolve this issue. If you'd like to email some more details to email@example.com, it will greatly help us to diagnose and solve that particular bug.
