Your game suffered from an unfortunate problem that might have been noted in the guidelines: Your screenshots contain your entire game! The hour I sussed this and changed out my screenshots for ones showing highlights (zoom-ins) of my game, my download-rate tripled.
That said, taste is what it is. I mostly left good ratings on a select set of goblin-related games that portrayed goblins in exactly the way I like to see goblins portrayed. 1800s dream-whatnot is not my deal, as might gobbies not be yours.
Cheers
