I was surprised at how fun this turned out to be! I think the main reason it works is because the designs are really good. I appreciate how there are so many cool colors in this. There are a wide variety of enemies and even the fact they shoot at you is different. While not as good as something like "RaidenX", still quite memorable. The sounds are nice and give it a good techno feeling.
You can't really shoot them off screen. It's even kind of cool how you blow up! It could probably use some more detail in terms of the background. I just appreciate a standard space shooting game. Good thing there's a shield.
