There are some somewhat simple things you could to make this better.
1. The player is OP: make there be less monsters but make them much stronger. And make the player weaker. Make the player afraid of fighting enemies. Being able to take on 10 enemies at once with barely a scratch does not instill fear in me.
2. Pacing: look at any of the great survival horrors many of them you don't even see any monsters until 10-15 minutes in. I know this game is shorter so scaling that down to about 3 minutes or so would work.
3.Music: really this is much more important then one might think. Put some ambient in there. There are many sites that have CC licensed music on them.
The game has good graphics and I don't see any bugs in it. All the things bad about the game are just design flaws.I really hope this helps in some way. There are not nearly enough survival horror games out there. I hope to see more from NarwhalGames soon.
Two things: The ship looks really out of place, make the ship look more basic or amp up the rest of the graphics. And add a mute button. Please fix those two things and you have a 5/5 game, as of now 4/5. And who the hell is trolling the comments thumbing down everything.
