Neat concept! The interactables are confusing at first, but once I got the hang of it, I enjoyed. The visuals and SFX also do a lot for that satsifaction.
The only thing I have to say about the gameplay- what prevents me from just locking all of them in the first floor, then opening the holes one by one? It seems like the most efficient way... Or is it intended to be played that way?
Either way- been a blast. Good job!
