Impressive work! Very cool story. It took me quite a while until I got the hang of the controls, and it was an enjoyable experience. I just wish the movement speed was a bit faster, especially since I soft-locked myself by activating the platform before I stand on it at this part:
I couldn't figure out how to get it to move back, so I just restarted the game =D. I then managed to decrypt all messages and reach the end.
Good game! Neat mechanics with the little robot and decrypting the signals. Well done!
