Devil Daggers but take it to the club - feels positively blissed out in comparison! Ludicrously addictive from the get go, few other games in recent memory come to mind with movement this satisfying and I've barely scratched the surface of the tech on offer. The dynamic leaderboard where you watch your name scroll up the list with every new personal best score is exactly the kind of feedback I wish more games provided as reward for performance too...anyway get in on the ground floor this is GOTY material easy.
