This is a nice entry! I originally thought this was going to be a sports game, but it turns out to be a WarioWare-esque minigame game! Can't say I am not surprised. I really like the hand-drawn art style, and the characters are all very cute and lovely. The minigames were nicely done, and I love the fact that you can mix and match them to gain a higher score! The game is generally really enjoyable, and I had fun until the end of the game. The main issue I am having is that the four original opponents felt like padding, and I would prefer the game start with the "masters" instead. Or you can have all characters teach one new trick, and that would be perfect. But I guess there are time concerns so that's that...
For some other criticism and suggestions, I think the animation played after the inputs is a bit long, and it gets repetitive halfway through the game. It would be best if the animations were played during the input instead of after them. I would also suggest showing how many points each trick provides clearly in the trick selection menu (something like +30 when you are hovering above a trick). Currently, it's a blind click spam and see which combination has the best points, and that felt awful. Speaking of the trick selection menu, it would also be nice to have the selected tricks highlighted if selected. It's quite hard to quickly determine which tricks are selected just by the text alone.
Anyway, this is suprisingly a very solid and fun game! Well done!
