Straightforward combination of Tempest and bullet hell games. It's quite clever, and does a lot with the premise. Your movement is constrained to a circle, and you must dodge bullet patterns and moving bosses while grazing bullets for your laser and damage powerups.

My main criticism is the controls are a little finicky. In most bullet hell games, you can hold a button (usually fire) to slow your character movement, to make weaving the patterns easier. There's none of that here, it's just raw analog stick input, which means you have to be ~extremely~ precise in your thumb movements to properly graze (which gives you bomb and score). Perhaps it's because I'm getting older, but the tension in my thumb started to hurt my hand after a little bit.

Well worth it for people like me looking for a unique take on some well-trod arcade design.
