The art style and music are cool, and I think there's a cool concept. There's definitely some stuff to improve in terms of execution. As others mentioned, the waiting between waves seems unnecessary and is kind of boring. It takes a long time to get your second tower, and even then the towers seem fairly useless compared to clicking. Also, it seems like the main sound effects are clipping. I think if you put some more work into this it could be something pretty cool. Cheers
