The art style is really charming and has a nice clean-but-slightly-creepy vibe, I love it! The concept of feeding the machine fits the theme so well, and the music being sweet despite the dark subject makes a fun contrast. Very addictive gameplay loop too, I kept trying to beat my own score.
The color-matching got quite tricky as the difficulty increases, sometimes I struggled to grab the right person because of hitbox overlap between characters. But for a solo dev project this feels really polished, congrats on a great entry!
