Nice, unique take on metroidvania. Good atmosphere and a fun central mechanic.
Like others, I struggled with the camera and the controls. I wonder if using a button for forward thrust and arrows to direct it might be more intuitive? I also had an issue with saving (I think). I thought I saved my game but after dying I was forced to restart a level. This was kind of demoralizing as it took me several tries to get to that point.
All in all, this is a really nice submission. Thanks for sharing your work. I look forward to seeing a future build that irons out some of the rough spots.
