Unused text in the game's files indicates that at one point in development, the developers had considered including a "Statistics" menu which would keep track of an assortment of miscellaneous in-game information, as follows:

Bolts earned
Number of enemies killed
Damage taken
Bolts spent on ammo
Shots fired
Damage dealt
Bolts spent on weapons
Nanomites (XP) earned
Time spent in Vid-Comics
Fastest play-through time
Number of objects broken
Time spent strafing
Time spent in 1st person mode
Time spent falling
Number of jumps performed
Number of deaths

This feature was likely scrapped early in development as no menu textures exist for this screen nor any option related to it in the Pause menu.
