Great little game! Its short, fun, the graphics look amazing, especially given that you made the game in 3 days, overall i had a great time. Good job!

You should tell the player the "E" key is to open the door. I have spent 2 minutes trying to open it haha

The game looks stunning, honestly. We also made one with Unreal Engine but it does not look as good as yours, so hats off! I like the idea although some of the puzzles were not very clear to me, like when you have "A, B and C" as options and the "Numbers of all doors". The rest are very clever and I loved the fun part before the end. Cool animation in the ending as well. Congrats!
