I don't mean to cause any offense, but is the game really worth that price? Honestly, if it were a solid game, I’d buy it without hesitation. The main issue is that without a demo for people to try out first, nobody will know if they'll actually like it.
I could give my opinion based on the screenshots, but out of respect, I prefer not to judge something without having played it. If this is your first indie project, let me tell you that this approach is a bad move. In fact, this is exactly how indie games end up dying. You need to offer something—at least a demo—because very few people will buy it like this. Without a way to test it, instead of constructive feedback, you run the risk of receiving massive backlash, which really hurts a new project.
