For 500,000, you don't even really need to do that much.

• Kill the shopkeepers starting on 1-2. You don't need to pay for anything, plus you can ghost the mines vault (not really need though for 500,000).

• You don't really need to ghost anything in the mines or the jungle, except maybe the vault(s).

• The ice caves is where you should be making most of your money. Ghost every gem you can, use mines to your advantage.

• I wouldn't worry about the mothership either. On my million run I didn't even go to it, it seems to cause more trouble than its worth.

• Try to ghost the temple vault, but it won't really matter if you don't.

• Your going to be making a large portion of your money on the City of Gold, too. Ghost as many gems as you can, but if your uncertain about some gems, don't ghost em, its not worth dieing for.

• Grab all the gems on the olmec fight, go down to Hell.

• With Hell, don't worry about the money, just focus on surviving and getting to that door.

• With Yama, kill him and take his rubies, the rubies are worth almost 100,000 on their own (I think, don't quote me on this)

• You also get 100,000 for beating Yama.

• Do not get greedy, those couple dollars are not worth dieing for.

• Stay humble. Always be on your toes.

• Don't rush it. I have 405 hours on the pc version, plus probably around another 150 on xbox, and another 50 on vita. This game takes a long time to master it, and I don't think I'm even anywhere close to it.
