I'm sorry but I do not call this a game, not sure if this is supposed to happen, there are a lot of bugs in there when u go so fast or out of the bounds, this happens 
for the gameplay: from what I understood you just got to hold D to run forward, and spam W to kill those enemies. there are a lot of bugs in there when u go so fast or out of the bounds, this happens
also no UI to show health, score story, or anything
the reason I came here was to understand what the theme meant, you said my game isn't following the theme, so I wanted to see what u mean
still, I do not see anything close to the theme in here. no death or beginnings? how is it following the theme
