Ah, used to play this in the arcade back in the day. This is a great game, and nearly identical to the original. The only thing that could make this classic better, would be to upgrade the control of the ship from left/right arrows to touch control like nearly all modern iOS SHMUPS. With that said, the gameplay is simple to learn, hard to master, and a blast to play. The frustration level decreases as you master the game. The Devs have provided an excellent options menu, but I don’t see auto fire there yet. I know this has been around for awhile, but I’d really appreciate an update for that. Thanks! (Also, the paid version deletes the ads.)
