The messages didn't show up for me, I don't know why that is. Also there is a bug on the first level, once I rotate it a couple of times there is a level in which I float even though there is a hole in the floor. Other than that a cool concept. (Not ready for steam though. Much more testing needed before you officially publish it on a platform like steam)
As for floating above hole in the floor: yup I know about this issue it's a problem with what's happening when you are standing in between of two planes. I am going to change it so when you turn the camera it will move character to the center of a block he is standing on.
And as for message not showing up I have no idea why :F
