What stops you from developing it further?)
Well, actualy nothing but time. I'm already working on Lustbane at my free time. So yeah, maybe I will make it my full time job some day, and then I will have more free time to small but fun projects like this. To be honest I had spent some time on weekend and made content filter, that I wanted to make in a first place, and a new secret to the game, I just having so much fun making it.
"I just having so much fun making it" - cool, that's the key for success - you should enjoy what you're doing! Lustbane looks fine, but very buggy currently. And broken parallax effect is really visible (at least to my eyes) - further plans must move slower than closer ones, not opposite.
