Implement points

[emurnane]

Score points for:

• 100 points for each wave (i.e., hour) survived

Each enemy killed, where points awarded depend on that enemy's size and speed:

• 10 points = slow enemy (5 or more recipients), 20 points = medium speed enemy (2-4 recipients), 30 points = fast enemy (1 recipient, i.e., the player)
• 10 points = small enemy (email length 1-xx characters long), 20 points = medium sized enemy (email length xx-yy characters long), 30 points = large enemy (email length greater than yy characters long)
• Display these points in the upper left hand corner of the screen.

We need to decide on xx, yy, and zz — so please test (i.e., play the game and write some info to the console) and respond with some details about email length: what range of email lengths are you seeing (min, max), and what's the average email length?
