It was nice after looking at the animations and the smooth gameplay. But is that all it has to offer?

The art was nice and pretty simple in its pixel form but nothing else changes. The background stays the same and the characters are just there.

The gameplay like I said was smooth and fast with ease to know how to place but there's nothing else to do other than to shoot. You can't even fly your ship.

There doesn't seem to be a storyline either. Or a description to what's happening. Or any other features like options? no options. Wow. the game is difficult and it ends fast without a way to get anything better out of it. maybe add more than just a "click and play" style after doing it again.
