It was super fun watching you try our entry "Diet Run" and the other games! I found you got a bit confused about how the game worked?
In short: if you eat too much fast food, the bar in bottom right will keep going right indicating "more fat". Meaning your stamina loss rate and speed will both drop significantly.
On the other hand, if you only keep eating healthy food your stamina won't rise fast enough but you will run faster and can jump over certain obstacles. So, the 2 obstacles and 2 foods side by side are all designed so you keep maintaining / balancing your diet.
Yeah, I know I know its a bit confusing. But its fun once you get the hang of it! ;) Thanks again for playing it!
