So... my ants got stuck and I don't want to restart because I saw the blanket. Here's my thoughts:
First, I love the pixel art. The colors are really vibrant and I always know where the path is. Enemies are easy to spot and avoid and the goal is easy enough to understand.
That said, the fact that I can't see all of my ants at once is pretty nerve wracking, because it makes me just want to move as fast as possible and not worry about if any of them get eaten.
I think that the intro where you say the different controls in pieces is pretty good.
All in all, it's a pretty game with an interesting concept, and I would definitely like to see this more as a puzzle game with shorter levels perhaps, than a giant, hard to manage maze.
