Shadow - 91

An on-rails, shootem up Im using to explore some design ideas, and play with a genre Im not familiar with. Depending on interest in the game, I will pursue it further and make it a more complete experience, eventually offering it for a premium ($1-$2). The gameplay is simple: point, click, blow up. Let me know what you think in the comments below. What would you add to the game? What do you think is missing? Any and all support is welcome! Thanks for playing!
