Cool game but I didn't get past the pizza part. I'm not sure how I was supposed to cut it... but I think my game gliched, since I somehow held the water for the plant while holding the pizza.
Do you have the latest version installed? If so, thanks for letting me know about the problems you're having. I'll look into them and see if I can fix the problem. To eat the pizza, simply place it on the cutting board once it's out of the oven and eat it slice by slice.
