What a great entry, I can see why this one is getting so much attention :)
I managed to get all bar two of the secrets for this one so I'll definitely be coming back later to figure out the last couple of images. This game had a really great "Aha!" moment very akin to The Witness. What's also great about this one is that it has prompted people to theorise and help eachother out to figure out all the secrets, as you can see in the comments of the game page. The devs should be super proud of that.
All told, an extremely polished and well made game that I'm 100% sure is going to do very well when the results of the jam come in ;)
