Surprised to see that I've already left a comment here as I don't remember rating the game. There's a few things I'd like to mention regarding the game.
I did not notice the humans until I've replayed the game, so I was wrong about the game being too simple; I also noticed the description of the entities in game which is pretty cool.
The screen SFX a is also great for creating atmosphere.
Generally the game is definitely a lot more dynamic than I remembered and a lot more fun.
The music is still really nice though.
