Yeah... and I think you definitely want some beats in there to help with pacing and timing... but maybe keep it up and have a "...." between those lines? Eh. idk. All I know is when the box hides completely, I still had my cursor there and thought I could move, so it just became trying to move it constantly to see if I had control back. :P
Also... no worries at all! I'm impressed by how much is here! I'll have to go in and try the other entries now :D
