Data & Analysis is a building in your base that automatically produces XP that can be collected by stepping on it while you're in the game. It also increases the optimal mining depth - the depth up until your pick becomes significantly weaker.
- At Data & Analysis Level 7 or higher, your optimal depth exceeds the depth limit of the game (2166.7) If you pass this point, your character is deleted and your chat is deleted, but not glitched like it was before.
- One theory for why you die is that Berezaa forgot to change the settings for the workplace. There's a property/option (FallenPartsDestroyHeight) that deletes falling parts when they reach a certain height to make the game run more efficiently. However, if you've ever been to 2166, you've seen that the mine still produces blocks below.
- Regardless of your optimal depth, the deeper you are (or layer of stone), the harder every ore (including stone) is to mine. Data & Analysis upgrades may decrease mining time which is increased based on your depth or type of stone.
- If you look at the computer screen the man is staring at in data and analysis, you will see a sideways Pepe the frog. It looks different in certain upgrades, like upgrades 7 and 10. At level 7, it shows a Pepe that looks like nightmare Freddy in FNAF 4 and a red background, possibly a reference to the fact that at that level you unlock depth 2000+, which is the underworld (needs link here). At level 10, it shows a picture of Peppa Pig changed to look like Pepe the frog.
