1. Also didn't expect the fall but it was really cool! I actually played through it twice bc I was a good boy who didn't enter the "do not enter" room thinking it wasn't finished at first before I realized Wait The Question Asks About Two Rooms so I went in there the second time around lol.
2. I found it particularly cool that some of the "conversations" in the beginning felt like they were actively referring to what I was doing, since I was reading the white text and then the orange text (roughly translated from what I remember) was like Hey Stop It Im Trying To Talk 2 You. Felt really cool, would definitely like to see more of it :0 Not sure if this would be too out of scope, but it would also be interesting to have "secret passages" where you totally ignore what the orange text is saying to find some other path to try and avoid the orange text.
3. It's very straightforward, I had no issues navigating the space!
