Thanks you so much for playing, and the detailed feedback!
I'm so happy the intended atmosphere came through, while I was making the game I kept thinking "yeah this feels nice and eerie but will people just think it's dumb?" The tutorial integration is actually something I've been doing since 2022, in my opinion it's a very brute force method, but it works. The low number of enemies is a bit of a holdover from the Waxworks influence, but also partly became forced by the technical issues the AI suffers from. But hey, who am I to turn away a complement!
I agree with all your points, originally the game was going to be multiple levels of the ship, and was going to play similar to the Kshatriya DLC in Metro Last Light where you repeatedly dive into the ship to pick up artifacts and restock on supplies. I think it was good I didn't stretch myself trying that idea though. The lack of feedback is also a sore thumb, there is little blood spurts that pop out when you hit an enemy, but since they move quickly and the heavy fog effect it can be hard to see. There is also a separate sound effect that palys when you hit an enemy, like a little stabbing sound, but it probably blended into the background too much.
There was going to be enemies in that area, specifically some that would ambush the player from the edges. But as you can imagine, just ran out of time to do it in a way that wouldn't have ruined the atmosphere.
Thanks again for playing!
