Interesting environment. I like the player character design, it definitely fits the theme of "You are the monster." I would love to know more about the background story here.
So there is an intriguing premise here, but much needs to be added:
-There is music on the title screen, but not during the game.
-There are some sound effects at the very beginning of the game, but not afterwards.
-There are some hazards to dodge, and the player can also heal, but there is no way to tell how much health the player has.
-The player character has no animation.
-After getting the upgrade and clearing the debris, I went into a dark area and could not figure out what to do next.
