Well, it's not that bad
It's not bad, but I see several major flaws. First off, and this is not a huge problem, the blood when you kill the frogs looks like crap. It just doesn't fit in to the otherwise well-drawn and animated game. Another thing, this one matters a little more, I can't see any way to get to level 2. After 1300 points and almost 100 dead frogs (25 escaped), I gave up, because I didn't see any way I could ever win or lose. It got boring. Also, I like the idea that you have to be constantly moving, but I got around that by just going all the way to the left and shooting the frogs as they came by. Maybe I let a few extra go...either way, you should mend this by either having frogs come from the left side as well as the right, or by having the movement loop or something - not sure how you would do that with frog movement or whatever...anyway that's just my two cents.
