Personally, I don’t think FPS mechanics would fit this game. The horror of the game doesn’t come from many enemies with many ways to counter them, but rather only one giant spider, with one way to eliminate it, being the main goal of the game. The more spiders idea is great if not too many and bigger play area, but I think this kind of one-enemy horror has great vibes. (I also support the other’s comment idea of having ways to distract the spider). Also, I think the current game is terrifying, so I think it would be good if this version was kept as a demo later, or just for fun (like how Minecraft keeps its old versions). (Apologies for not the best english:) )
