Where do you get keys to make so many puzzles and "Extras"?
I don't understand ,in @belugawhale's challange, what means six particles of filt, (and other repetitions).
New hint for Stage 2!
Solution:
Stage 1: First, you have to download the image. In the upper right corner, it tells you to open it using 7-zip. Open up 7-Zip file manager, then double-click on the image, and you will find two files, erc.zip and password.cps. The zip file is encrypted with a password.
Stage 2: Copy the .cps file to <powder toy directory>\Saves\ and open tpt. Control-click on the Open button to open a local save, and you will find a sign that says "Password: " and some pixels. The trick with the pixels is to take the first letter of each pixel's element, or the number of repetitions if there are more than 1 in a column. You should get "aec5bib6t6" as the password. Type that password into the zip file and you will decode "erc.txt", which contains the ERC.
