Honestly, I have no clue what the story is about. Clearly, I am dumb.
Now, excluding my lacking sapien in homosapien, the game was good. It had a story to tell, and it told it directly.
Each character was interesting and, although it was a bit tedious to interact with them all, the number of characters always decreased so it is all good. However, the random bits of dialog sprinkled everywhere really helped the game greatly. Dialog when you die, dialog when the game starts, etc. Little details like that really can make the game more dynamic, and I appreciate it.
I don’t really have many suggestions. I will say that, in the first room, at the top-middle, behind the tree, you can walk out of bounds. It was so easy, I first thought that was a hidden ending.
Also, You should probably make the bullets a bit more visible. Either bigger, have more usage of black and white together in design, or make them animated. Having some visual indication which enemy is which would also be good.
