Pit and Field

The field expanded 82 squares forward due to powerups.
The pit was expanding at a rate of 3.0 seconds, so that it reached a maximum y position of 166 and consumed all of the field.

In total, 414 items spawned.

Nifty earned a total of 300 points. Here is how they achieved that score.

116 points were earned by collecting ordinary items and powerups. This makes up 38.67% of their total score.
36 points were earned as a result of 11 special bonus items being collected. This is 12.0% of their total score.
They were responsible for the destruction of 13 cannons, earning them another 130 points. This equates to 43.33% of their total score.
Unfortunately, not realizing the detriment of inaccuracy, the player threw 1 rocks at... well, everything but... the cannons! This cost them 5 points. It's too bad really, because they could've had a much better score of 305 points. Aim better next time!
Finally, due to their speed in collecting items, they earned an additional 23 points. This is 7.67% of their total score.

10 platforms spawned. 10, or 100.0% of these were consumed by the pit.
33 cannons spawned, and 20 or 60.61% of these broke due to Gods Attention or some other unfortunate and cacophonous calamity. The other 13, or 39.39% were dispatched by a player!
The cannons shot 37 balls at Nifty. They jumped over 30 or 81.08% of them, while an additional 5 or 13.51% of the balls fired missed completely due to our faulty aiming system. The other 2 or 5.41% were direct hits.

Also, a total of 13 rock throwers spawned, and 1 or 7.69% of these broke because... I think they were just too stupid to get out of the way of the pit. Or maybe, God hated them!
Back to the cannon balls though, some of them did work in the player's favor. In all, 4 cannon balls hit and destroyed rock throwers. This equates to about 30.77% of all throwers spawned.
The throwers shot 38 rocks at Nifty, hitting with 1 of them which is about 2.63% of the time. The other 37 or 97.37% of the rocks missed them because I think that these damn throwers are blind or something. Like can't you guys aim?
The player grabbed 13, or 34.21% of all the rocks that fell.
In addition, they were given 23 rocks by rock supply reload powerups.
They threw 28 rocks. 27 rocks hit cannons, whereas 1 missed. As a result, Nifty's accuracy was 96.43%!

In the end, it was a pit that killed Nifty
