A rather light side-scrolling shooter featuring the now common neon-trimmed graphics.
As far as side-scrolling shooters go, this isn't a tough one. You've probably played harder, almost certainly so, depending on how often you pick a game from here. This features graphics made popular by ABA Games titles such as Tumiki Fighters and Gunroar.
While it does have the glowing outlines down (and hence the title of Glowy) it neither has the polish, nor gameplay. That's not to say it's bad - it's just a different type of shooter. An easier type.
The game features mostly shooting right while enemies come from that direction. However, it also employs the enemies coming from above, below and behind technique which is usually frustrating but here is used quite well. In the end, you'll have to decide whether you like it or not.
