Glad you did everything yourself :) Game is very easy, maybe enemy should be faster or have more hp. Also, I missed a music and sound effects. For example, when you shoot or enemy die. For me, I don't know does the game end. It will be nice to see some for example vertical bar (like minimap) where your ship was in this road. And on the end of bar something like skull to know about boss fight. I am very happy about your first finish game jam keep going :)
