Just played and beat it, over all i like it, but theres some stuff that bothered me a little. i wish the POIs were a little more distinct from the surrounding terrain, as it stands right now sometimes it feels like im just photographing a rock that doesn't look very distinct from the rest of the terrain. i also would've preferred the game told me that there would be a ding when i got a good photo, or that the game would check it off for me, i had to look in the comments to figure out if I'd done it correctly. it may also be a good idea if the launch location was marked on the map, but that depends on how much you're expecting the player to pay attention.
I'd like the robot voice to be a little more clear on what it's saying, the only thing i could pick up was "hull breach" after the power outage, other times it just sounded like gibberish.
i'm not sure if the power outage was a scripted event or not, but it felt like it. this may get in the way of the movie accuracy bit, but i think it would be cool if there was an actual power meter that would run down as you moved, and then the power outage event would occur when it runs out, maybe add a mechanic to restore a small amount of power before it runs out
i also wish there was more interaction from the monster, i'm not even positive i saw it during my playthrough, aside from what i think were some tentacles? since this is more of a survival game than the original it would be cool if there were times when the monster caused problems for us, like if it got to close we either had to run away, or sit perfectly still until it passed, it would make the gameplay slightly more engaging.
i really enjoyed my time with this, and i hope you continue to improve it, because i would love a version of iron lung that felt a little more "video gamey" so to speak
