Thank you for the feedback, that really means a lot for us ❤️❤️ (it's my first gamejam and the first comment I ever got😄).
Sorry if the puzzle looks too complicated 😥
We can give a hint : count the blinks...
And about the corridor, it's just a long hallway used as backdrop....
Thanks again for the feedback, we'll maybe do a update with more hint for the puzzle...
