As a big fan of both Alien Planet and Myst, this was a real treat! Really fun to get out my notepad and jot down the map as I played, write notes, etc. Absolutely loved the vibes, the puzzles, and I really enjoyed the 'unlocking senses' mechanic. The length was also a pleasant surprise - didn't even notice the time passing!
Unfortunately I did eventually get stuck (possibly bugged out?) after I entered the 3 digit code. Nothing seemed to happen and I couldn't re-trigger it, and after re-checking every room and DOOR I couldn't figure out how to proceed (clearly something with the bells?). But it's very probable I just missed something.
Anyway really fun little game, great job mates!
