Amazing art and a well thought out game. It felt a bit repetitive after while though. I would have liked to see a little bit more of a puzzle element instead of simply find the picture and flip it.
But for a gamejam game an amazing submission.
I have no experience with UE so dont know i possible. but i always advice people to have a webbuild available. Usually i'm on linux so can play windows games, and beside that i have to dowload the game, tell windows its ok to play, wait for my virus scanner to say its ok before i can play it so it a long time before i can play it.
