Strange. I ran it with a neko build, set a timer for one minute, and the text remained the full time. I ran it again just to check. I don't see anything in the code that would cause it to do that.
The only thing out of the ordinary I found was it asked for a library called thx.csv in project.xml.
I don't know what library that was references so I removed it like so:<!--haxelib name="thx.csv" /-->
If you do know what it is and what it's referencing and the problem occurred with that file then try removing it if it's not critical.
Hope that helps.
