Finally able to rate games, I see inspiration from many other puzzle games. I found the mechanic to be easily understandable and you took the work to actually voice over this so yes, definitely credit there. I was a bit doubtful about the last puzzle***spoilers*** because it's a trial and error one where the answer (if you get the tip from the wall), is either one of the two words, thus leading this puzzle to be time consumming rather than mind bending if you know what I mean.
Overall I found it to be enjoyable!
