Loosing motivation :(

I got really far my first night, this morning I don't feel that motivated. I don't know why. Maybe my game idea sucks. I don't know. I'm going to take a break and come back in a couple hours and see how I feel about it then.

Here is a screenshot of how far it is now.

Anyone have any suggestions on helping with motivation?
