Pit and Field

The field expanded 20 squares forward due to powerups.
The pit was expanding at a rate of 3.4 seconds, so that it reached a maximum y position of 80 and consumed about 80.0 % of the field.

In total, 103 items spawned.

Jonny earned a total of 101 points. Here is how they achieved that score.

48 points were earned by collecting ordinary items and powerups. This makes up 47.52% of their total score.
27 points were earned as a result of 6 special bonus items being collected. This is 26.73% of their total score.
They were responsible for the destruction of 3 cannons, earning them another 30 points. This equates to 29.7% of their total score.
Unfortunately, not realizing the detriment of inaccuracy, the player threw 3 rocks at... well, everything but... the cannons! This cost them 15 points. It's too bad really, because they could've had a much better score of 116 points. Aim better next time!
Finally, due to their speed in collecting items, they earned an additional 11 points. This is 10.89% of their total score.

6 platforms spawned. 5, or 83.33% of these were consumed by the pit.
13 cannons spawned, and 8 or 61.54% of these broke due to Gods Attention or some other unfortunate and cacophonous calamity. The other 3, or 23.08% were dispatched by a player!
The cannons shot 16 balls at Jonny. They jumped over 10 or 62.5% of them, while an additional 4 or 25.0% of the balls fired missed completely due to our faulty aiming system. The other 2 or 12.5% were direct hits.

Also, a total of 8 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, 1 cannon balls hit and destroyed rock throwers. This equates to about 12.5% of all throwers spawned.
The throwers shot 19 rocks at Jonny, hitting with 1 of them which is about 5.26% of the time. The other 18 or 94.74% 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 9, or 47.37% of all the rocks that fell.
In addition, they were given 5 rocks by rock supply reload powerups.
They threw 11 rocks. 8 rocks hit cannons, whereas 3 missed. As a result, Jonny's accuracy was 72.73%!

In the end, it was a rock that killed Jonny
