1.The rooms at the end are a bit weird I guess mainly because the prototype ends right after. It would be cooler if those rooms lead to something more. The individual effects in there are cool though.
2.The conversations are endearing and distinct. It is pretty clear. They have plenty of varieties too, its easy for this game to turn into like a long hall with a lot of text, but its pretty spread out.
3.Sometimes its hard to know to walk to the side.
The fall is good. I expect even longer fall and other things in the full version!
