Is there a difference between worlds?

After a 90 day survival run, I decided to try out the Teleportato and move on to a new world.

So, now I'm in World 2, and I want to know if there is any difference between the worlds?

Obviously, the map is reset. And, you bring some of your items with you. (I found out the hard way that my unequipped backpacks in inventory burned to ashes! -- Probably due to a side-effect of the Pack-In-Inventory mod.)

But, as you advance worlds does the game become harder in any way? (e.g. Do monsters have more HP or do more damage?). Or, is it just a reset of the world which allows you to change characters, etc.?

Solution 1:

When you activate the Teleportato in Sandbox Mode, you will receive XP for the days that you have survived and be able to change characters.

Going through the Teleportato will keep your current inventory and all of your prototypes.

This new world is only going to be different geographically. The monsters have the same HP and attack power; they will behave in the same way as you would find them in your first world. You are just generating a new world to exploit explore!
