Fat Knights has been posted about here before here. However, this post provides something new: downloads (offline versions) of the games and brings attention to their new game, Fat Weather!
For those unfamiliar, a brief synopsis of each game follows.

(Note: The offline version expects you to run an HTTP server and will not work correctly unless you do. It is provided for modding, game preservation and for looking around the assets. If you want to run the game locally offline, I suggest using the http-server package on npm/node. Disabling some CORS restrictions on your browser may also work. e.g. chromium --allow-file-access-from-files)

English Translation
A mini-game where you dodge falling food. If you touch falling food, it will be absorbed as calories and converted to fat.Depending on how fat you got, there are multiple endings. You can view previously seen endings from the Gallery. The difficulty settings do not impact your ability to get an ending, so choose your difficulty appropriately to suit your goal.
The Maid character is unlocked after finishing the game as the Mage at least once.
Summary
A mage apprentice was hungry when she stumbled upon a spell that would allow one to turn rain into food. When she cast the spell, a great storm of food began to fall. However, this food was unusually high-calorie and was digested instantly upon contact with one's skin.It is recommended to use the “Play on the Big Screen” button to play the game.

Download Scripts
You do not need these to play the games. They are provided to show my methods for archiving the game which may be of use to other reverse engineering or archiving efforts.
Fat Knights has some resources baked into the JavaScript files directly as reversed base64. These image resources are reformatted back into proper images and stored in the ciphered_images directory. Note that changes to these files will not be reflected in the game for this reason.
