Hey, nice game!
The entire opening sequence feels so polished and the menu art is so dynamic! I also think your choice of music compliments the art and creates a really nice atmosphere for the game! I also appreciate the fact that you took the time to make a cutscene at the start to set the tone! I made it to roughly round 10 or so before i succumbed to my allergies, but my main criticism is that the exact wave I got up to was not displayed on the ending screen.
Overall, I loved your game! If you have the time, come and check out ours too!
