Hello ! Every section in the game are independant from one another, so you shouldn't get stuck on an area. Maybe if you explain to me which problem blocked you, I may help you?
I understand your point on the control scheme, especially the escape button. Getting stuck rubbing on wall is due to the player hitbox being a bit huge but as it wasn't game breaking, so I focused on other elements.
I hope the experience wasn't too bad even if you didn't make it to the end !
