An odd amount of lag happens when I engage enemies in combat and when I open and close the inventory/pause screen. It is also tedious to have to experiment with ingredients because I thought I could make a jelly filled riceball but mixing aita berry+rice/rice ball didn't work, mixing sweet berry syrup+ rice/rice ball didn't work, and then finally I decided to combine berry jam+ rice ball and that didn't work. Maybe I had the worst luck but either more hints need to be in the ingredient descriptions or I should be able to pay someone to learn a random missing cooking recipe. I eventually got the "jelly doughnut" but not after failing to find a cooking guide.
