The tennis mini-game has been fixed it seems. Less bounces and as such less speed build up.
But the Maki running has been chronologically been: impossible, extra hard <{idk which came before which}> time consuming but easy if you tap in a somewhat slow rhythm, impossible, and now again extra hard.
Idk when i played the sports festival but it worked well for me. Weightlifting worked how it was supposed to. The running was hard but gradually easier as it was programmed to be. Pong/tennis caught me off guard how hard the first training session is, but it also became gradually easier. I think i wanted to bite off my fingers during and after the running sports event. Which worked but was hard.
