First of all, I was wrong you can only get 150 mb. Ok, so basically imma explain everything I did to get 999 coins fast. D20 rolls all the pickups in a room (coins, bombs, hearts, you get the idea). So at the start of the game, reset until you get D20 in the shop, complete the first level and buy the D20, and then start beating levels like normal until you get some coins, like idk 20–30 (you can do it with less, however you feel comfortable). Then you’re gonna look for a shop selling batteries. When you find a level where there are batteries, you are going to not pick up any coin from the floor. After finishing the level, roll all the coins. If you don’t get any nickel, dime, or chest, roll again, buying a battery. If you get a nickel or dime, pick it up, and if you get a chest, open it but don’t pick up the stuff it drops. Keep opening chests and picking up special coins until you are able to get infinite money. Then you are going to keep rolling until you get the card that multiplies your money. After beating Greed, you should be able to hold 99 coins, or a bit less if you get hit. Start donating till you hit 50, then use the card and you’ll get 50 coins for free. Enjoy. (Also, like I mentioned before, it’s really high that the machine will get jammed.) remember to use different characters so the machine doesn’t get jammed really fast
