Awesome game. Well done.
Can do with some tweaking for the spawning of the projectiles but love the fact that there are 2 endings.  I also had one ending with Hidden knowledge 2. Wasn't able to replicate it though but you can see it in the stream. 

Very short game, Enemies are slightly scary. 

Im not sure what in this game fits to the theme, perhaps the amount of smoke particles are making the enemies unseen, when we will spam shooting,
