Kid Vector is the kind of game we need more of. It's fueled by a love of the genre and a desire to have fun. It doesn't attempt to cash in on what's popular at the moment or be a clone. It does its own thing, and it does it with pizazz.
I found the game to be a real challenge, which seems hard to find these days. For $2, you'll be getting a retro game that you probably won't be able to beat too quickly (unless you're some kind of pro).
