What are the differences between difficulty levels in SOTS: The Pit?

When starting a character, there are four difficulty levels:

Easy
Normal
Hard
Insane

What changes based on the difficulty chosen? The wiki shows that experience gained changes, but is there anything else?

Solution 1:

Yes, a lot of things seem to change with difficulty. From a quick look at Easy, compared to my regular runs on Hard (and a few early peeks at Insane):

• Experience you gain decreases with difficulty.
• You get more health on level-up on lower difficulties.
• Your damage decreases with difficulty, enemies' damage increases.
• Stronger enemies appear sooner and more often on higher difficulties.
• More map objects (boxes, recharge hubs, stuff like that) spawn on lower difficulties, and new objects seem to appear sooner on lower difficulties.
• Map objects seem to spawn damaged or ruined less often on lower difficulties.
• More and rarer items drop more often on lower difficulties.

What does not seem to change:

• Hunger and food
• Durability, power, ammo and repair mechanics
• Traps
• Status effects
• Number of charges in hubs and crafting stations
