Yooo great minds think alike! A very similar concept to my submission. I really like it. I'm going to try to get a better rank (I got 2:30). One suggestion I'd give is having the clock count down from 4:00 to 0:00. That's what I did on mine at least. At one point I had forgotten that the limit was 4:00 so I wasn't sure if I would die. Great work! (edit: I just got B rank, I found some shortcuts, there are probably more. Love it, great level design!)
