Oh, good catch. Both E and F are assigned as "Interact" keys in in the Input Manager, It must've kept F as a secondary key and I never checked it. Thank you for playing it and for your feedback! There are some areas missing colliders so you fall through it that I will need to fix. And yeah, it looks like the camera issues are common for everyone. I'll tweak those values or change some settings with it.
Thanks again, I'm glad people are enjoying the game despite its issues!
