If you're still into endless runner, what about endless runner with these:
1. There are random ingredients that you can pick on the road/track. Picking any of them will give you just 1 score but you can avoid all of them.
2. You have shopping lists with random ingredients request in each of them. One list could have only 3 items but one could have 7 items. Picking correct ingredients based on certain list will reward you with big score. The longer the list, the bigger the reward, ex: 3 item list gives 10 score while 7 item list gives 60 score.
3. Picking incorrect item will cancel and remove a list and the list will be replaced with random list couple seconds later.
Yes the goal is to earn highest score as much as possible by fulfilling the lists. You can choose the limitation : traps, timer or something new?
