Spoilers:
Your game was interesting, especially once I got to the end and realised that there were multiple endings. I really liked the use of sound and music to enhance the dramatic bit towards the end. I found it quite easy to get lost, I guess some landmarks or a map/minimap might help? Or maybe the sprite assets used weren't distinct enough. I also found that unlimited ammo and stationary "enemies" made the game very easy, but I guess those black things aren't really your enemies...
Good demonstration of consequences in a jam game! I went through it again without killing anything and I was left with the things I spared. I didn't understand the link to the theme until the end, when it revealed you as one of the black things. It was your family they were ordering you to kill?! Subtle, but I like it. Thanks for making, I had fun :)
