Woah! This is seriously cool! The animations are awesome, they feel really fluid and slick. Reminds me of the old skewl stick wars animation series on Youtube from 2010s era. E.g. Slush Invaders type vibe. Very cool! And the colour matching was really interesting – I struggled a lot with it, but it was definitely a cool idea. I didn't feel it fit the theme especially strongly, but I know it's quite broad and open to interpretation. I'm thinking if you're wanting to expand this out later on, you could explore the mechanism for switching colours in more depth. I felt like in order to improve at the game, the skill was mashing C and stopping with fast reflexes. But wouldn't it be interesting if you could combine primary colours to make secondary colours, and the game took on more of a puzzle feel? Anyway just one direction idea. Nicely done!
