You know... I don't get it...
I will admit that after watching the other episodes that this one isnt as high grade as the later episodes, but I think you shouldnt necessarily remove it from newgrounds. I felt that this one was still pretty high grade for what we've seen come from you.
Keep this one still on here, i don't see any reason why you should remove it from newgrounds. Even if you did remake it. Other flash artist keep their original works up and its always nice to check back and forth to see the grounds crossed overtime.
