My submission for Ludum Dare 43, 48h compo. The theme was "Sacrifices must be made".
Instructions: WASD or arrow keys to move, mouse to aim and click to shoot.
A few minor improvements have been added to the original version, such as skippable story text and menu sound. The original Ludum Dare version is available here: https://ldjam.com/events/ludum-dare/43/downgrade
