Its very impressive you two made so many distinct mini-games, such an anthology is quite the undertaking for a game jam!
I really love the audio, great work on that front. The graphics are nice too, they all look like they fit together well, though naturally with the split-focus nature of the game no one graphical aspect was too impressive.
Some nitpicks:
-Its odd the tutorial is exited by pressing the x key when the rest of the game is entirely mouse driven, to be honest I didn't even see the small instruction at the top left of the Tutorial panel instructing how to close it and I just intuitively tried to click off the screen, and ended up clicking the Play Button while the tutorial panel was still up which was momentarily jarring.
-I was wondering why I had trouble going left sometimes but it turns out its because my mouse was off the game's screen. Which, fair enough, that's reasonable, but a wider aspect ratio could help alleviate the issue so the knob isn't quite so close to the left edge of the screen.
-I experienced a glitch on the circular 'pong' game where the ball didn't bounce off the edge of the paddle; it registered as two hits but kept moving out of bounds undeterred
-The ski game seemed to come and go REALLY fast compared to the rest, I lost the first time with nary registering what was going on and likewise won the second entirely by accident of having the knob right where it needed to be at the start.
