The overall feel of the game is kind disconnected so it doesn't really feel immersive. I think you can really lean into the horror angle with the cthulhu theme. I also don't think its a good idea to give all 4 mini games and let the player see all the upgrades right away. I think if the player have to work and play to unlock the mini games then there is a mystery element to draw players in and make them play. It could also be cool if the mini games are more narratively connected so that it ties into a thematic story.
