I liked it, however I got stuck on puzzle 13, is there a way you could subtly guide the player?

Thanks a lot for taking the time to play and leaving a feedback!
Puzzle 13 is a hard one for sure. I just added a hint system: press H in any puzzle and you’ll get a light nudge first, then the plan if you still need it.
I also moved that room near the end, so the learning curve is smoother.
Hope it helps, and let me know how far you get!

Oh good to know! Will give the game another try and see if I can beat it!
