Thanks for the nice comment and feedback! Yeah I feel the same, it's very close to an okay experience, I caused the spawning bug in the last hour, and I wanted to make the unlock system clearer visually in the game. I did have a bunch of thematic text in mind too but I decided to try text-less for some reason. But yeah I think there's good potential in the whole concept!
Also, I will say that at least 2 people have said that they looked up what the spleen does after seeing the game :P
