Thank you!
That was actually a suggestion a playtester gave me. The thing was, I had 15 minutes left on my timer and I had four key things left to do: audio, post processing, death feedback, and end screen. Audio was top priority because it's one of the rating criteria; then I needed post processing to improve the visuals, and death feedback so players wouldn't be confused if they suddenly die. There was no time left for an end screen, though it's obviously too late to add one.
