i really liked the atmosphere and the controls were good! past the first puzzle, it became really hard to read the messages. the speakers were pretty quiet and it was hard to tell when a code was starting and stopping, the shadows being the hardest imo, but i did still manage to work my way through the puzzles sorta through luck and context clues. it's a really cool concept! and i probably partly struggled with it due to just not being very adept with morse code lol. regardless, very good job!
