Great game! You had a large team and managed to get everything done yourselves huh? Nice, the art is very well done and it surprised me how nice it was for the intro, however, the lack of sound for the intro was jarring.
Once underwater, constant bubbling noises from movement, ocassional bubbles from breathing and so on help set atmosphere as it's constant and always there, the gutteral monster growl was nice, it gave the sense of a threat, but what I came across wasn't nearly as bad as it sounded, which was slightly disappointing. I also like the work that went into the shadows and light obscuring.
There's a few problems however, the flashlight, there's plenty of indication from it crackling and flickering before it goes out and breaks, but I expected the little bar in the top left to at least tell me how much is left. Also, whilst you have controls on your page, it's always important to have the tutorial in the game itself.
The flares, they're limited light sources once the flash light goes out, but they are too dim and last too little to be a good marker for anything than an instance of light, making people grope in the dark. Which is fine for atmosphere and if that's the intention you're going for, but it can get tedious and frustrating since you can't even see anything, if not careful with guidance.
I had honestly expected the flare to be brighter and last longer than it did for a limited resource. It was much easier when I restarted and was careful with my flashlight isntead of using the flares, which helped greatly. I just sort of expected underwater flares to last longer at least.
There's a problem with playing the game when using the pause menu to exit out and retry, the text boxes don't show up again. Also, it's possible to escape and just go through the boundaries of the top of the map, past the black texture at the top and into a flat green, endless space. I restarted it and escaped the glowing tendrils all the way back up, but nothing happened, does this have an ending?
However, great work on the game! It was fun to experiece the atmosphere and soundscape. With all original assets, it must have been quite the work.
