Unfair challenges. When i say unfair i mean i had two infinite booster for a time period and even with them I couldnt clear level 109 (i had instamt cook too). It is impossible. I have to make 41 dishes in 78 sec but maximum customers just come, waste 5 sec and ask for one dish. The game seems rigged... Edit: i see devs saying levels require skills but are passable, thats a lie
