Really strong puzzle that had me pulling out the pen and paper. Figuring out each individual mechanic felt rewarding, and the atmosphere and music were great. I think the first 'hint' in the description should be stated within the game, this is because not only does the player not know the mechanics, but we also don't know the goal, making this functionally impossible without at least the 1st hint (unless it was decipherable through the loading quotes, in that case I missed it). Solid entry.
