Pit and Field

The field expanded 31 squares forward due to powerups.
The pit was expanding at a rate of 3.85 seconds, so that it reached a maximum y position of 98 and consumed about 88.29 % of the field.

In total, 91 items spawned.

Jonny earned a total of 75 points. Here is how they achieved that score.

35 points were earned by collecting ordinary items and powerups. This makes up 46.67% of their total score.
22 points were earned as a result of 6 special bonus items being collected. This is 29.33% of their total score.
They were responsible for the destruction of 2 cannons, earning them another 20 points. This equates to 26.67% 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 80 points. Aim better next time!
Finally, due to their speed in collecting items, they earned an additional 3 points. This is 4.0% of their total score.

7 platforms spawned. 6, or 85.71% of these were consumed by the pit.
15 cannons spawned, and 12 or 80.0% of these broke due to Gods Attention or some other unfortunate and cacophonous calamity. The other 2, or 13.33% were dispatched by a player!
The cannons shot 24 balls at Jonny. They jumped over 15 or 62.5% of them, while an additional 7 or 29.17% of the balls fired missed completely due to our faulty aiming system. The other 2 or 8.33% were direct hits.

Also, a total of 9 rock throwers spawned, and 0 or 0% 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, 3 cannon balls hit and destroyed rock throwers. This equates to about 33.33% of all throwers spawned.
The throwers shot 32 rocks at Jonny, hitting with 1 of them which is about 3.12% of the time. The other 31 or 96.88% 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 14, or 43.75% of all the rocks that fell.
They threw 10 rocks. 9 rocks hit cannons, whereas 1 missed. As a result, Jonny's accuracy was 90.0%!

In the end, it was a pit that killed Jonny
