trustymutsi: I really wanted to like this game, but it starts too brutally hard.
Yep, even on creative mode the hoards interrupt the tutorial/resource gathering, as it says that you'll only have to fight monsters in the dungeon; NOT true, you get bombarded with the pesky fucks as soon as they show up, and they keep spawning so much that you can't even get resources!
I suppose you'll have to keep battling them until you level up; then you can focus on resources, but my guess is that the hardcore crowd complained as per usual; and the dev changed the difficulty... I'm thinking of refunding it for credit as my money stays in this store, but I'll give it another shot!
EDIT: Read this on the steam forums, very valuable advice!

How to Commander Vile
Killing Commander Vile stops the Corruption of It from spreading and stops monsters from spawning on the surface! Until you kill Vile, the corruption will keep spreading.
SPOILERS:
Since Vile is not very smart, you can cheese him in a variety of ways (similar to how you can cheese most monsters, especially in Normal difficulty worlds). If you want to kill him very fast, I'd advise you to do so - he hits hard and has a lot of HP.
For example, you can stand on a pillar of dirt and shoot from above. If you're melee you can stand behind a pillar of dirt with one block dug out and hit through that. If there's a hole, he'll stand on the other side and look at you while you shoot him. There are surely even more ways, but let's leave it here.
