Most of these (minus the brightness) have been resolved with updates I did today, I haven't released it yet because I'm doing a ground up polish to fix all the errors that were made during the last days crunch. At this rate it should be out before the judging period ends but I know that will not allow the rating to be changed since it wasn't submitted by the deadline but I feel like I owe it to the project to at least get something out of it.
As for the green light that is supposed to be when she is "captured" and triggers a fail of the first puzzle as well as an extra bit of dialogue to continue to the next segment. This also works properly now but sadly the judged version will not have this. Thank you for the testing though and I hope you come back to check it out when the update hits.
Edit: I also want to mention that the updated release will actually have a small selection of options on the settings menu that should make it run significantly better on lower end hardware so that should make things easier.
