Nice update. BUT...I know I'm a hard critic, sry for that^^
BUT, bright red text on gray ground looks awful. The ALT+TAB bug is fixed. The Music isn't crap anymore but dear Level Designer (I dunno which one of you 2 do that) PLEASE remove that shadows from the walls. I have literally no idea if I'm hitting the wall or not.
But since it's a nice challenging maze, you got there way more stars then before.
Since you uploaded that on 2009 I don't think you still work on it but it could be better.
