Small bug fix

Thank you to everyone for the support on Duskbound so far! I will be back in some time to write a longer post-mortem about the process of making my first visual novel as a solo dev, but for now I come with a small update/bug fix.

The earlier version of the game had an error with unlocking one of the CGs in the gallery, this has now been fixed. I've also added a choice to return to earlier endings once you've seen the final ending, so you're no longer stuck there if you wish to replay!
