Difficulty is like spicy food: you're never going to please everyone. This game was actually a bit easier initially, and people complained about that. Ultimately, I have to take a balance of what the general feedback is, combined with my own taste, and come down somewhere. For now though, I'm reasonably happy with where it is. Sorry it wasn't quite what you were looking for though.
I'll also point out that this one is free, so the risk/cost of someone checking it out is minimal.
