Great concept!
A little easy though. I was playing with a horrendous mouse that gets stuck and I was still able to make 1644 I think (that's when my mouse finally failed me and I couldn't get all the fruits).
Couple of changes would be nice. Like maybe making different levels with different objectives, such as cutting only apples or bananas. Maybe bonus rounds after those games such as hitting as many pesky hamsters!
Graphically a couple of things that bothered me was the fact that it said golden fruit when the only golden fruit available was an apple. Make other golden fruits.
A combo score of greater than 5 would be nice too, since I was able to get combos of up to 8 and I only round up multiple 5 combos.
Powerups like slow motion or something might be good too. Just some suggestions. I liked it though!
