oh wow, good find!! Haha thanks for bringing that to my attention, I'll be sure to fix that right up.
If you're looking for the "C" ending... you don't HAVE to go night fishing...
Dang, I probably should've tried that myself!
Also, during the final sequence, you can avoid your pursuer by examining an object before he captures you. He'll happily glide past you for a bit before returning, and you can slingshot him around the cabin. I used that opportunity to see if there was anything I missed in that brief chase, but couldn't find anything.
Hahaha thank you for breaking our game and letting us know! Truth be told, this kinda stuff keeps us up at night so it's so helpful to know what needs to be fixed. Thank you so much and consider it fixed!
