This is a fun game, and I'm such a fan of TD games (I play a bit of Bloons TD 6 almost every single day, before going to sleep)
I like the overall mood of the game and presentation, and the twist on the TD genre. However I must confess I kinda skipped the color mechanics because I found that having neutral turrets was more beneficial in the long run. So I ended up playing it like a regular TD.
There is definitely a lot of work here (models, animations, etc), and I like the art style. Good job!
