Guxt is a tiny Shoot-Em-Up created by independent developer Pixel, who previously released Cave Story.
Gameplay is simple. You fly your space ship though the vertical stages, blasting everything that comes in your way. Speed and weapon upgrades makes life easier. Each stage ends with a boss fight.
The game has a distinct look and feel aimed at reminding you of classic Gameboy games. With only 5 stages the game is not too big, but will require a lot of training to beat.
