Nice idea, great job!
It had a few issue though. When I started the game, I was very low and the start button was always behind me, even when re-centering the view.
When I started the game, it took a while to work out that the egg plant reduced the number (it would have been good for the sign or something to mention that first). Initially I was just chopping fruit and didn't know how to reduce the number to fit the answer. Seemed a bit random too, sometimes the count would go up by 2 even though I only chopped one fruit.
I eventually got the idea and got the win game screen, which was nice...
Also, I'm left handed, so it would've been nice to have a swap hands option.
Other than that, a nice solid entry to the Jam and it had a good feel to it.
