I probably would have liked this more if I had not played so many shmups.
There's just... nothing after a 1CC. This is definitely an "average" as it gets, I would have brought it to 2 stars purely out of personal enjoyment but the art gets a little bonus.
The story is just there.
Did a scoring run once and ended up close to the top 10. Trying to score more would result in minuscule but rough improvements needed (not shooting missiles being more lucrative at times??? then what is the gimmick for)
Has more hazards than bullets.
etc

Get it on sale and give it one try if you're interested I guess.
