the aesthetics work out super well! The animated backgrounds and enemies make for a surrealist environment that feels alive. As for gameplay, I wish the projectiles would de-spawn a bit quicker or on impact, by shooting a lot I found that the level can get filled with your projectiles and it becomes difficult to move around. Another plus to having the projectiles disappear on impact is to give the player a sense that the hit is acknowledged, and the enemy will eventually die. I was in a situation where I could not tell if I was hitting the right thing or not because there is some missing feedback. The story in combination with the style you used has a lot of potential though!
