Thanks for the comment! If i had even one more non-work, non-family day to work on it, Many of those things were on the to-do list! My last day i had to pick n choose some stuff. And even polish what needed to be done.
But to note some stuff from number 2, there is a boss counter in the spawner menu. And quickly seeking through your video, it looks like you didn't get the victory screen? I'm sorry. i will get like 20 minutes of time later today, This may be one thing i might be able to look at and change. its suppose to pop up when you kill 5 and show you the time it took you.
