If you ever want to do a 100% run, but you already collected the coins, you need to reset them in a way. So I spoke to the developer about this and there is a way. First you go to C:/users/your_name/appdata/local/ink . Remember that appdata is a hidden folder, so you need to show hidden folders. Then you go into the file called DontModifyThis en yes, we will modify it. Every 2 you find in this file should be changed to a 1 if you want the reset the coins. 2 Means you have collected the coin, so by changing it to one the save file tells us we didn't collect it. I did this a couple of minutes ago and it worked for me, so have fun with the hundos!
