Love the atmosphere and the art! Especially the character art! The music and sounds effect also really put you in the mood!
I was abble to go around 750 metters, don't know if there's more content deeper?
I think a little bit more attention to the fact that my whole crew DIED would be great ahah, i was horrified at first when the submarine broke. A sentence or two to acknoledge their lost would be great imo.
At first the controls where quite unintuitive, but when i understood that i had to go slowly and steer when slowing down/lifting, it felt better and really felt like controlling a submarine at the end of a cable.
I wonder how the levels are generated?
I also really liked the pickable lore pieces, would be great to be able to bring them home and have some unlockables/be able to read them again (thinking of the wildcard ahah). Idk i really like the idea of having a lot of crews sinking there over generations, i think a feeling of time passing would add something to the experience!
Anyway! Incredible game, congrats! And i just noticed that you did it alone, wow!
