Nice game! I was only able to get to the parachute and the two final keys. I couldn't figure out what to do with the final code and the morse code. Short, sweet, and logical.
edit/update: i know this is like incredibly late but i feel obligated to tell you, after you finish everything in the first tower room whatever its called, do the pattern ".._ _.._.(down down up up down down up down)" in the second room and youll be able to use the last two keys
