But if you are getting other achievements on the way for map tubes/dynamite/or picks, be aware they might not pop up when you go back online. Obviously once the final upgrade shows up you can go back online before buying it. Warning 1: You are offline, so achievements won't pop immediately. I mentioned this to a friend who had gotten stuck with only getting shield upgrades, and he had a slightly different experience. I tried again and saw that I had kept those two upgrades. I got two upgrades I needed in a row, then went back to my earlier save. I decided to just suicide after reaching the store and see what would come up a few times. My personal experience was I had gotten both heart upgrades and then after reaching the next 2 stores and reloading several times at each was only seeing shields. You can repeat as many times as you want, easily getting 100k each time if you are on later levels.) I'm going to go through all the warnings/disclaimers first before covering the process.

Finish the level, then go back to your earlier save. (Back up at the end of a level where you earned a lot of gold, like one with a bonus mine. You can abuse this to get 5 million gold. But a few things will carry over, notably upgrades purchased (although they won’t be visible until you have (I think) started two new levels, including respawning with the amulet), and lifetime gold earned will go up (but not the amount you have in game). You'll be back to where you were at step 1. Relaunch the game and click play, it will ask you if you want to use your online or local save. Relaunch, and play or do whatever you want. (Either use airplane mode, turn off your wifi, or disconnect/disable your ethernet as appropriate.) 2. I'll detail this method since it's applicable to more people. You can do this by playing on two different devices (which gives you a bit more flexibility) or on a single device.

To do this you need to be able to 'save' your game and go back to an earlier version. There is a pretty handy exploit you can use to make this WAY quicker than normal.
