1. Do enemies spawn more frequently?
The enemy spawn rate is unaffected by the amount of players.
2. How does money scale
Whenever a player picks up some money, everyone in party receives the money.
Whenever someone spends their money on anything, it comes out of their own pool of money, without affecting other players.
3. Do enemies have more health?
No, the health of enemies is unaffected by the amount of players.
4. Do items and crates appear more often
No, and this is the main reason why coop is not easier with more people. The item and crate spawn rate remains the same regardless of how many people are playing and when someone picks up an item, no one else can pick it up anymore and only this player will receive the effect of the item (with some exceptions mentioned next).
