Rubber ducks! RUBBER! DUCKS! How cute is this?
Ehem. Anyway, it took me a while to figure out what one has to do (I kept happily resetting time at first, since I thought I get more spirals, so more points that way... Yes, I am stupid.) The game loop (pun intended) is nice and strangely satisfying. Add some more graphics to it, and please make the music less dissonant. (The BGM and the click sounds are out of tune at present.) Then that will become a really fun game.
Oh, one thing: Sometime the duck gets nearly stuck in the loop. Usually, it's automatically forward moving on the yellow lines, but somehow, sometimes it doesn't and then one needs to jump to move forward. I guess that's a bug...
