I guess that's one way to explore the theme. I couldn't really figure out what I was doing. Even after scrolling down to find the tutorial text (It's always just off-screen, somehow, with these games,) it was still unclear if we were supposed to be dodging or collecting things. After dying numerous times, I realized that we were meant to be collecting the things that look like video game bullets, and dodging the things that look like insect food. But the icing on the cake was when I let the game run on its own, and the weight of the leaves pulled my fireflies together just right to dodge and collect stuff, and I ended up getting more points by accident than I could ever by pressing the button intentionally. (One point. I got one point that run.)
Why not just have WASD controlling the left firefly and Arrow Keys controlling the right one?
