I really really enjoyed playing this!
It's so exciting whenever I find new things and read the entries. The satisfaction of peeking out a porthole and finally seeing them is so fun, akin to being a kid again and discovering something you've never known before. All the luminescence is delightful, both in and out of the bathysphere.
Interaction with the bathysphere and the environment through valves in levers is such a neat idea and I think it's executed well. Perhaps a more minute detail but I like being able to watch the valves spin and the indicators go up and down.
The method of dealing with fires is lit. Admittedly I'm not very good at it yet, I turn the valves way more than necessary. :.P
Making it to the bottom was really hecking cool, I hope I didn't miss too much of it with my frantic attempt to zoom to the bottom while the bathysphere's hull was breached and on fire.. I misplaced my nano tape.
Music being there was nice, I really liked how it sounded and I think it fit well. It helped me feel less nervous than I would have been otherwise.
I did end up getting one or two critters stuck in the bathysphere but I didn't mind it since it ended up feeling like they decided to join me on my journey. :.)
Thank you for sharing your game with me!!
