Excellent! The game is very pretty to look at and I liked the idea. Felt somewhat refreshing to give enemies some love instead of killing them.
Graphic wise, I found it a bit weird that when moving the character seemed shaky, as if it had some judder. Also I had no idea what was that thing the enemies shoot at you. Other than that, amazing art! I liked the main menu moving when you waved the mouse, the font fit very well to the "machine" ambient. The transitions between stages was amazing and I liked the weird portal that took you to the next stage.
The path finding on the enemies worked very well. I'd just make the visible area for the cupid a bit larger because in later stages it got real hard to navigate when lots of enemies are coming after you. I managed to get to floor 4, thought the difficulty progression was rather balanced.
The audio is responsive but feels weird at times. The song during gameplay doesn't seem to fit the environment, but maybe that was by design.
Also, one minor thing was that sometimes a line artifact would show on the screen, as if some problem with rendering a single frame. Maybe that was just some WebGL shenanigans.
Overall, beautiful game and quite fun! Congratulations!
