Prolog is a short-n-sweet endless* shoot-em-up made in the Love2D framework, featuring:

Stylized Graphics
A four-track OST
Simple controls
Many, many bullets to dodge.

Controls:
Arrow keys to move, shift to move precisely.
Z to shoot normal gun
Hold X to shoot special gun
The special gun takes a moment to start shooting and drains ammo quickly, but it does more damage and pierces through the armor of most enemies. Ammo is replenished by hitting enemies with the normal gun.

IMPORTANT NOTE: While there are no official ports of Prolog to Linux and Mac systems, the .love file should work just fine with the appropriate Love2D interpreter. See install instructions for details

ANOTHER IMPORTANT NOTE: I made this game with the sole purpose of learning Love2D. While I am greatly satisfied with the result, don't expect a great game.

*techically, there are only 100 complete levels. Once you get to level 101 you'll fight an unbeatable version of the stage 1 miniboss. Good luck actually getting there, though, that'll be a brutally long and difficult endurance challenge.
