Yer, I do need to update a few things. With getting stuck on the walls, if you stopped moving would you drop to the ground?
There is a slight bug when jump and going over the 20 distance limit. Something I need to work on.
You will need the blue and green keys to progress through each door.
I did have some extra conversations at the start of the game to explain how to switch player. I'll add those back in.
There will be updates coming tomorrow. Hopefully you can give it another go :)
