Some good old-fashioned arcade action. The graphics are right out of the early 8-bit era, doing a lot with a little.
The music was pretty annoying, though. I'm not sure if it is supposed to sound like that.
One thing that would really help a game like this would be some kind of gradual progression that changes the nature of the gameplay and escalates the challenge over time. For example, more feathers spawning (and you have to catch them in the same amount of time), more spiders (and you have to avoid them all), and so forth.
Also, it's helpful to write the controls on the page. I died once or twice before figuring out that I move with the arrow keys. I was trying to click, press WASD, Z, and so forth. :)
