Nyahax is a loose remake of Galaga that features thirty stages to play, boss fights and even the occasional power-up items to collect for ship upgrades. Players are given a total of three minutes to beat the entire game, but you can earn some extra time during the bonus rounds that comes after every boss fight.

Don't forget to turn on the autofire option when starting your mission if you want to avoid getting blisters on your fingers. (source: babara)
