Anyway, for constructive criticism:
Personally, I like the mechanics. The spawn rates seemed fair, the RNG was good, and over all a good idea for a game.
The audio used too many real life samples and sounded unnatural with your voice. In the future, use an SFX program to generate the audio.
As for graphics, they're good for a basic game, but you need more practice with graphic design before you can start making your first "real" game.
Overall, A very good game for a beginner, but if you're looking to be in a competition like a game jam, you're gonna need more practice.
