Thanks! I used real deep underwater ROV footage for reference in making the game. It really is as creepy down there IRL as it is in the game.
Some other people have mentioned issues with the tasks being too boring, so I'll be sure to fix that.
The only truly scripted event in the game was the spawning of the bigfin squid at the end, which looking back on it, isn't that great since the other events (mainly random noises you hear) occur on a random basis, and only a random basis, so I might want to change that in the future (as well as adding more levels of course).
The random alien/ambient noises I mostly made myself by recording random stuff such as moving chairs, opening/closing doors, and other household sounds, then slowing them down. I also used a bit of image to sound conversion.
There is, however, one specific ambient noise (that has 3 variations) that I did not make, and that is the "Bloop" sound effect, an actual recorded unknown sound recorded underwater.
Anyways, sorry if I waffled on for too long, I just find this game to be the most interesting out of all of my games so far.
