Protogalaxy did not impress me. It's a pretty straightforward arcade game: seperate controls for moving and firing; try to manage both as best as you can while you're being bombarded by up to a dozen enemies at once.

The tutorial it thin. But what really put me off is that it's the kind of game where you might play a 5-minute level for 4:30, fail at the end, and then have to start the entire level over. Bleh. The repetition is painful.

I do not recommend this game.

SHMUP+Upgrades+Coop = Great but, without really any online community to speak I suggest you buy this game with 3 others if you plan to really enjoy it.
