Small game!
Gameplay itself wasn’t too bad, in fact I quite enjoyed running around and changing color to try and deal with the hoard more efficiently. I would personally love to see it flushed out a bit more in the future.
However, outside of gameplay, I got to mark off some points. Your UI inappropriately scaled, making it impossible to fully read the story and to see my essential elements. This left me with guessing more than anything. Outside of that, the artwork was comprised of primitives, which is fine for a concept but makes for an ugly looking final game.
For a concept, this was straight to the point and very much showed how much fun it could be. However, for an independent game, I feel it needs much more polish and love than it was given.
