This is one of the most interesting, unique, challenging puzzle games I have ever played. I streamed this over a 12 hour stream I had on twitch and me and all of my viewers were insanely invested.
Penguin Parade takes you to a remote island where there are doors scattered around for you to go through and complete puzzles. After completing them you get to save a penguin from the level. The teaching penguin mechanic was the most interesting way to progress a puzzle I have ever seen. Not being able to do things yourself and having to teach an AI to do it for you was so much fun and made a handful of levels very challenging. This wasn't just a ten minute game jam game. This unironically took me 4 hours to fully complete. This was an amazing title. The only complaint I have is I wish there were a few more prompts on core mechanics. There was some times I had to do some experimentation that I felt I shouldn't have had to do. Other than that it was a great experience and must play for all puzzle lovers.
