This is a crazy art style. Same as the other comments, it's like a mix of neon lights and pacman game. But all the animations are so well designed. With the mechanisms also well polished. I really enjoyed a lot playing. Although it's hard to understand what happens at the beginning, but after learning a while it soon gets wild.
I also meet the issue that other people are mentioning. By continue playing it, the game fps gets down to 10 so probably a performance issue with all these animations - although these are really really great.
The rougelike design is also a lot of fun! The "more enemies" can even be an option haha that's so funny.
Congratulations! This is a really nice tower defence game. It's very unique and well polished. I love all the things!
