No offense mate, but if you're getting others to write scripts for you, that tells me all I need to know about how in-depth your role in making this game is going to be.
Also the level design options in those screenshots makes very little sense. E.g., a spiked, wooden walkway between two walls with no easy, visible means to access it.
Honestly, you have to consider, first and foremost, whether people will go to the effort to even spend an hour or two downloading it for free.
Ultimately, you need yourself a Unique Selling Point. What does your game do that others do not, and why should the end user care enough to pay for it?
Sorry if that comes off as harsh, but hey, welcome to the world of business. People want the world for a penny out here.
