I see. Well, in that case I have different feedback to give. Firstly, it's generally not a good idea to mix mouse and keyboard controls without letting the player know you did so. I only used the mouse the entire time and saw no reason to think there was anything else. Secondly, I notice your game page doesn't mention any controls. That'd be a good thing to include if it's not going to be mentioned in-game.
edit: oh, nevermind. It hadn't refreshed for me yet.
