Thank you for your review and for playing the game !
I don't have much experience on designing puzzles, so it was a bit hard balancing how explicit the clues had to be, without directly telling the solution to the player. My only playtester also said that the second level was a bit too hard, I tried adjusting the hint but it's still a bit tricky.
Taking note on the map was definitely a feature I wanted to add since the beginning, but I focused on other aspects of the game and didn't have time to do it at the end. And for the audio part, I kept telling myself I would do it later, only to run out of time at the end. I would say the main issue I faced during this jam is time management ^^ I'll try to improve on that for the next one.
