You totally nailed it with Kings Field! I didn't know it existed until we made the project.
The platformer definitely could have used some...platforming and especially the parts with the hills at the start where weird, you kinda have to Skyrim jump up the right place until you don't slide down, and yeah, the part after is really barren.
Can confirm that the bug you mentioned exists, and is consistent to replicate, there are unfortunately other parts as well where you can get stuck, wish we were able to fix them before the deadline and some other goofs like the inventory getting messed up when you have more than 3 items and smaller details like the Beaver at the bridge needing 10 logs from you...but never actually taking them lol.
Thanks for your constructive feedback!
