First of all, I immediately loved it because I am a sucker for an animated main menu.
Game is nice! The little tutorial for the decryption was a bit confusing at fist, but I managed to push through and cracked it. Does the code change on a replay?
Other than that, I thought the dialogues could be shortened a bit and also the walking felt painfully slow even for the very little walking that there is to be done.
Lovely 'vintage' models too, and overall a really nice game
