Cool game. Original idea.
I really liked the art on the characters and the tubes, lots of colors, love it.
I initially thought that the game is working against the theme because the more of them I control the harder it is, but then I realized that they act as a multiplier. Nice add there to fit the theme ;)
The camera would needs some improvements as a lot of times some of my characters would go off screen and I can't really see them anymore in the game screen.
If you have a chance please provide feedback on my game.
